Issued in limited editions, these  eminently  contemporary  timepieces feature a new cushion shape and a  design  inspired by one of  the brand\u2019s first wristwatch chronographs  introduced  in 1928. At the  heart of these generous cases with their  reinvented  aesthetic beat new  calibers \u2013 entirely designed, developed  and produced  in-house \u2013 focused  on monopusher chronographs. A first  version  equipped with a split-second  function sets slimness records  with its  ultra-thin self-winding  movement measuring just 5.20 mm  thick, while a  second model stages a  fascinating tourbillon and the  third variation is  equipped \u2013 like the  original \u2013 with a pulsometric  scale. Representing  elegant horological  complications that are some of  the most highly  sought after and most  complex to produce, the  monopusher chrono-graph  models are complemented  by a ladies\u2019  double-pusher chronograph. A trio  of dual-time watches  housing a new  in-house movement rounds off this  unusual range of  timepieces. Like  the other most recent creations from  the Manufacture,  these special  editions bear the prestigious Hallmark  of Geneva. <br \/>\u00a0<br \/>Founded  by  the youthful Genevan master-watchmaker  Jean-Marc Constantin in 1755,   Vacheron Constantin is the world\u2019s oldest  watch manufacturer engaged in   uninterrupted activity since its  creation. On the occasion of its  260th  anniversary, Vacheron Constantin  is introducing the first  exclusive  models of a new collection. Named  Harmony and featuring an  entirely  reinvented cushion shape, this  eminently contemporary  interpretation of  horological excellence signed  Vacheron Constantin  draws inspiration from  the architectural lines and  distinctive design  of the first wrist  chronographs made by the  Manufacture in the late  1920s. Through its  perfectly balanced  three-dimensional  \u201cshape-in-shape\u201d approach, Vacheron  Constantin once  again demonstrates  its expertise as a watchmaking  sculptor. This is  achieved through a  sophisticated case construction  dedicated to  precision, readability  and comfort on the wrist, while  pervaded by a  disarming apparent  simplicity. Moreover, this new generous  and boldly  distinctive  silhouette complements the existing range of  round or  tonneau-shaped  cases characterising the classic collections by  the  Maison. <br \/>\u00a0<br \/><strong>The reinvented cushion shape\u00a0 <\/strong><br \/>The   seven  first references in the Harmony collection, presented this year   in a  limited anniversary edition, are dedicated to chronograph and   dual-time  functions through four new calibers entirely designed and   developed  in-house, along with an evolved version of an existing   chronograph  movement. This sculptural collection intended to host   innovative  in-house developments displays a resolutely modern design,   while the  generous lines of its cushion-shaped case lend themselves to    accommodating medium complication and grande complication calibers. <br \/>\u00a0<br \/>Once    again demonstrating the dual nature of its horological expertise,    distinguished by the art of shapes dedicated to time measurement,    Vacheron Constantin has devised an innovative construction of the    cushion shape that has been part of its range for almost a century. A    curved case middle, a square bezel and a round watch glass meet and    mingle in an elegant reinterpretation of the monopusher chronograph with    pulsometric scale presented by the Manufacture in 1928. While the    inspiration derived from the original model is immediately perceptible,    each detail has been infinitely rethought, right the way through to  the   specific ways that light reflects off the case, in order to offer a    unique and unprecedented shape, combined with optimal comfort. In the    same way, each element of the dial and hands inspired by the original    watch face has been reinvented to guarantee perfect readability of  the   functions. <br \/>\u00a0<br \/><strong>The chronograph in the spotlight <\/strong><br \/>The    in-house calibers housed in the Harmony collection feature major    technical and aesthetic innovations. For this anniversary series    preceding the launch of the full mainstream collection in 2016, Vacheron    Constantin celebrates a complication that has enjoyed a key place   among  its creations since 1917: the chronograph. Interpreted in its   most  elegantly classical expression \u2013 the monopusher chronograph \u2013 this    collection greatly prized among connoisseurs requires considerable    patience, dexterity and experience on the part of the watchmaker who    assembles it. Four first models in this new collections embody the    expertise of the Manufacture in the measurement of short times: the    world\u2019s thinnest monopusher split-second chronograph, with its    self-winding Caliber 3500 measuring just 5.20 mm thick: the monopusher    tourbillon chronograph, driven by manual-winding Caliber 3200; the    monopusher pulsimeter chronograph, with manual-winding Caliber 3300 \u2013 a    variation directly inspired by the 1928 model; and finally, a    double-pusher ladies\u2019 chronograph powered by manual-winding Caliber    1142. <br \/>\u00a0 <br \/><strong>New in-house calibers <\/strong><br \/>Stemming from   seven  years of research and development, the three new monopusher    chronographs presented in the Harmony collection are driven by calibers    entirely developed and produced within the Manufacture Vacheron    Constantin, completely in keeping with its watchmaking heritage while    benefiting from cutting-edge technologies. While the architecture of    these movements reflects the traditional aesthetic of Haute Horlogerie    chronographs and their classic column-wheel construction, the design of    these new calibers enjoys the best of modern manufacturing processes    providing a wealth of advancements in terms of materials, precision,    functionality, aesthetics and user friendliness. Reflecting the same    approach of combining tradition with state-of-the-art technologies, the    development of self-winding Caliber 2640DT \u2013 which also began in 2008 \u2013    delivers a new addition to this innovative range of in-house   horological  complications by providing a dual-time display. Two elegant   masculine  models crafted in white or pink gold, as well as a   diamond-set white  gold feminine versions, are equipped with this useful   complication  featuring an elaborate mechanism enabling easy  adjustment  of all  functions via the crown. <br \/>\u00a0<br \/>More than ever,  technical   sophistication combined with a unique aesthetic are  dedicated to   differentiated time measurement through various new  calibers and   complications: <br \/>\u00a0<br \/>\u2022 Time measured and sequenced: the chronograph and split-second chronograph <br \/>\u2022 Time captured and simplified at a single press: the monopusher <br \/>\u2022 Precise time: the tourbillon <br \/>\u2022 Time linked to the heart: the pulsimeter <br \/>\u2022 Offset time: dual time <br \/>\u00a0<br \/>In    keeping with the finest watchmaking traditions and like all Vacheron    Constantin creations, these new calibers are adorned with remarkable    finishing entirely performed by brilliantly skilled artisans. Mirror    polishing, bevelling, circular graining and C\u00f4tes de Gen\u00e8ve are merely    the most notable examples of the countless finishes patiently applied  to   components that often remain hidden from sight. Stamped with the    prestigious Hallmark of Geneva, they meet the numerous demanding    criteria of this independent and sovereign label that is a guarantee of    origin, of precision, of durability and of watchmaking expertise. <br \/>\u00a0<br \/>In    addition, so as to single out the seven inaugural timepieces in the    Harmony collection, issued in limited editions, a scrolling motif    inspired by the balance-cock on the oldest pocket watch belonging to the    Maison and signed by Jean-Marc Constantin in 1755, variously adorns   the  oscillating weight, the chronograph bridge or the balance-cock of   these  models. Also known as \u201cfleurisanne engraving\u201d, this refined    ornamentation is reserved for the Vacheron Constantin 260th anniversary    special editions and a commemorative inscription is duly engraved on   the  back of these highly exclusive timepieces. <br \/>\u00a0 <br \/><strong>A contemporary projection of the finest horological traditions <\/strong><br \/>The    inspiration for the Harmony collection can be traced to a historical    model with a distinctive character, equipped with an extremely elegant    and sought-after complication: one of the first chronograph  wristwatches   introduced by Vacheron Constantin in 1928. This  monopusher chronograph   with a yellow gold cushion-shaped case was  equipped with a 13-ligne   caliber displaying a pulsometric scale around  the rim of the white dial   punctuated by leaf-type hands and painted  Arabic numerals. Originally a   medical instrument, the pulsimeter  chronograph enabled doctors and   nurses to take fast readings thanks to  the chronograph hand showing the   pulse rate after 30 beats on a  graduated scale. When placed side by   side, the chronograph and  original version show undeniable similarities.   The aesthetic reference  is immediately apparent and the kinship is   accentuated by the innate  elegance of the monopusher mechanism. Driven   by their extreme  perfectionism, the designers and developers at Vacheron   Constantin  have nonetheless gone well beyond merely modernising a   vintage model.  Each detail, each line, each curve, each characteristic   and each  reflection has been rethought so as to offer a contemporary   projection  of Vacheron Constantin\u2019s ancestral expertise. On both   technical and  aesthetic levels, this ultimate reinterpretation of the   1928  chronograph has given rise to an authentic work of art. <br \/>\u00a0 <br \/><strong>The multiple facets of a horological work of art <\/strong><br \/>The    traditional cushion shape is thus transfigured by a three-dimensional    \u201cshape in a shape\u201d architecture, while the movement it houses is a    distinctively Haute Horlogerie mechanism featuring a unique construction    coupled with exceptional reliability and performances. This  resolutely   contemporary and sophisticated construction, combining a  curved case   middle, a square bezel and a round glass, highlights a  silhouette graced   with dynamic curves and multiple facets. Imbued with  a blend of purity   and equilibrium, the aesthetic of the case creates a  perception of   finesse in terms of its volumes, while the profile with  its stretched   lugs provides a flowing, continuous surface for the  light to play over,   yet without in any way being simplistic. This  quest for perfect harmony   in lines, curves, facets and reflections  expresses the artistry  deployed  by Vacheron Constantin in creating  horological sculptures  destined to  host finely crafted movements. A  true virtuoso when it  comes to shapes,  the Manufacture excels in  highlighting the most  complex mechanisms  through a unique aesthetic  stemming from an  authentic artistic approach.  Designed to enhance the  readability, the  precision and the practical  nature of the movement  they house, these  perfectly proportioned volumes  provide a first-rate  showcase for the  Vacheron Constantin and serve to  accommodate a wide  variety of  complications. Destined to become brand  classics, the new  timepieces in  the Harmony collection are part of a  modern and daring  universe in  which technique meets the art of shapes in  a remarkable  horological  sculpture.\u00a0 <br \/><br \/><strong>A face radiating supreme purity <\/strong><br \/>While    the medium complication and grande complication calibers unveiled  this   year naturally deserved a case on a par with their inherent  excellence,   creating perfectly readable dials corresponds to the same  standards of   ultimate refinement. In this instance, the inspiration  drawn from the   1928 chronograph gives rise to intense  reinterpretation: each original   characteristic is re-embodied in the  most original possible contemporary   expression. Designed with an  admirable concern for details, the shapes   of the numerals and letters  as well as the colour choices were  carefully  thought through in order  to perfect the limpid nature of a  complex  display and to reinforce its  unique aesthetic. The elegance and   sophistication of the monopusher  chronograph are thus displayed with   great distinction in a luminous  silver-toned dial featuring painted   Arabic numerals and slender  leaf-type hands. Entirely redesigned and   resized to compose an  entirely original creation, the blue painted   numerals of the Harmony  collection give a unique smoothness to the dial \u2013   placed extremely  close to the hands in a striking visual effect \u2013  along  with  incomparable legibility. While this reinterpretation  preserves the   original spirit and elegant classicism of the 1920s, it  lends a unique   personality to the new Vacheron Constantin line. Imbued  with an  entirely  reinvented historical dimension, the \u201cleaf\u201d shape of  the  hands  characterising the 1928 model also makes its first entrance  in  the  current Vacheron Constantin collections. The slender, elongated   shape  ensures the excellent precision required by these elaborate   movements,  while the purity of their outlines radiates an exquisitely   refined  traditional charm. The delicately blued chronograph hands mark   off the  specific functions of short-time measurement, accentuating the   clarity  of the displays translating the intricate workings of such   complex  mechanisms. In a subtle contrast with the deep blue of the   numerals and  hands, the minute circle graduations, on which the   pulsometric and  tachometric scales appear in a vivid red, thereby   reinforcing the  excellent readability of these gracefully uncluttered   dials. <br \/>\u00a0<br \/><strong>Horological sculpture: the art of shapes dedicated to the measurement of time <\/strong><br \/>With    the 3500, 3200, 3300 and 1142 calibers, Vacheron Constantin pays    tribute to the chronograph \u2013 a complication that has been a key part of    its watchmaking heritage for a century already, since it was back in    1852 that Vacheron Constantin created its first pocket watches with an    independent seconds hands on \u201cmedical chronographs\u201d featuring a    dedicated graduated scale on the dial. In 1873, the Manufacture created    its first pocket chronograph, and in 1917, it miniaturised it to    wristwatch size for the first time. These first models reflected the    specific requirements of watch mechanisms capable of measuring short    times with extreme precision. Thus, from an early phase in its history,    the Vacheron Constantin Manufacture developed expertise in the    development of highly technical complications and timepieces, capable of    performing scrupulously accurate time measurements, resistant to    extreme conditions or intended for scientific observations at sea on in    the air. These capabilities are notably apparent in the number of   orders  for antimagnetic chronograph watches or chronometers that were   met  between 1880 and 1910. Such requests stemmed from doctors, military    observatories, engineers or navies. Vacheron Constantin\u2019s horological    science has been gradually honed and extended throughout its history,    and the art of \u201csculpting time\u201d in order to meet highly demanding    specific needs is admirably embodied in the Harmony collection. <br \/>\u00a0<br \/>While    the cushion shape was first introduced in the 1920s to showcase one  of   the brand\u2019s chronographs, previously used in a pocket watch, this  same   approach has guided the creation of the new Harmony collection.   Pervaded  by a powerful sense of dynamism and modernity, the unique   aesthetic of  these new models is dedicated to serving the precision and   readability  of the elaborate functions. Its sophisticated  construction  raises  Harmony to the rank of a horological sculpture,  while the  un-usual  movements inside it offer a multi-facetted vision  of time. <br \/>\u00a0<br \/><strong>Chronograph: tradition reinvented <\/strong><br \/>Composed    of two Greek words \u2013 chronos and graphien \u2013 which together mean    \u201cwriting time\u201d, the chronograph is designed to measure short and    medium-length events. Fulfilling one of humankind\u2019s oldest dreams, that    of mastering time, the chronograph evokes speed and power in the minds    of collectors and connoisseurs of Haute Horlogerie. This has made it   one  of the most sought-aftercomplications since the birth of the   mechanical  watch in the 1980s. So as to provide a fresh demonstration   of  excellence in writing a new page in its history, the Manufacture    Vacheron Constantin has chosen this complex and refined function to    inaugurate the Harmony collection. From 2008 onwards, the Vacheron    Constantin engineers, designers and watchmakers set to work, guided by    the same spirit that inspired Jean-Marc Constantin in 1755 when he    opened his workshop in the Saint-Gervais district of Geneva: developing    the most accomplished timepieces, driven by the most daring  techniques.   From the production of the first watch bearing the  signature of   Jean-Marc Constantin to the launch of the Harmony  collection, 260 years   have elapsed, witnessing the birth of some of  the world\u2019s most   complicated and sought-after chronographs, all  bearing the stamp of   Vacheron Constantin\u2019s ancestral know-how. In  1917, the Geneva-based   Manufacture presented its first wrist  chronograph. Ever since, it has   tireless perfected this demanding  complication, in order to offers its   owner the freedom to write his  own time and to control it in a   comfortable, elegant and assured  manner. <br \/>\u00a0<br \/><strong>Technical and aesthetic innovations <\/strong><br \/>While    the chronograph is a highly coveted complication that has appealed to    connoisseurs around the world for almost two centuries, its  production   proves a highly complex process, due to the many mobile  parts composing   it. Thus, when the Vacheron Constantin research team  began work seven   years ago on creating a new chronograph movement, the  aim was clear: to   create a movement with a classic architecture,  while making the most  of  the materials and technologies of  contemporary watchmaking. To  ensure  its refined elegance and in  tribute to the creations produced by  the  Manufacture in the 1920s and  1930s, it must have only one pusher.  Yet  behind the apparent  simplicity of the chronograph lies a difficult   complication calling  for great dexterity and precision in order to   master its adjustments  and enable the owner to enjoy the inimitably   smooth and comfortable  feel of a single pusher. In the course of the   development process, the  objective became even more specific: the   chronograph movement was to  feature a traditional column wheel and a   lateral coupling clutch,  while incorporating highly ingenious advanced   features such as the  \u201cdragging\u201d minutes counter and the new \u201cfriction\u201d   technique for the  lateral coupling clutch. The latter manages to address   the problem  that sometimes impairs the running of a chronograph:   pressing the  pusher tends to make the chronograph seconds hand give a   slight jerk  before starting to run. The chronograph was thus entirely   redesigned  in order to reduce and even eliminate this tiny jump. <br \/>\u00a0<br \/>Pursuing    the crucial goal of developing a perfectly functional, reliable and    user-friendly caliber, the quest for perfection was carried right the    way through to the smallest details, such as a cone-shaped gear between    the winding pinion and the crown wheel in order to achieve pleasantly    smooth, gentle winding. Moreover, these new movements also benefit  from a   cutting-edge technology that served to make an extremely  precise wheel   profile guaranteeing minimal clearance between the gears  \u2013 with the   teeth separated by barely 0.03 mm! Other technical and  aesthetic   achievements set the finishing touch to these new calibers  combining   beauty and technicality. Whether visible or concealed, these  refined   details embody the watchmaking art according to Vacheron  Constantin,   revealed in the chronograph gears shaped in the form of  the Maltese   cross, or the screw holding the column wheel and also  adorned with the   brand emblem. <br \/>\u00a0<br \/><strong>Haute Horlogerie finishing and anniversary decoration <\/strong><br \/>Like    all creations by Vacheron Constantin and bearing the prestigious    Hallmark of Geneva, the new calibers of the Harmony collection are    adorned with the finest Haute Horlogerie finishing. Among these    artisan-style finishes, the most remarkable of which are black or    specular polishing, bevelling, circular-graining and C\u00f4tes de Gen\u00e8ve.    Entirely hand-crafted by specialised artisans, the decoration of all    parts, including those invisible to the naked eye, requires not only a    thorough learning process but also great dexterity and intent    concentration. Driven by the constant concern for excellence and    perfection that sets an authentic Haute Horlogerie apart from the rest,    Vacheron Constantin masters more than a dozen different types of    finishing. <br \/>\u00a0<br \/>So as to further enhance the inherent distinction of    the inaugural models in the Harmony collection \u2013 issued in limited    series \u2013 and to ensure them a lasting place within this exceptional    celebration of the history of the Manufacture, the Vacheron Constantin    designers have created an exclusive movement decoration specifically    dedicated to its 260th anniversary. The design team, which normally    focuses in the watch exterior, thus had the privilege of dreaming up an    original motif inspired by the arabesques that adorned the  balance-cock   of the oldest pocket watch belonging to the House and  signed Jean-Marc   Constantin in 1755. Also referred to as \u201cfleurisanne  engraving\u201d, this   decoration also appears on the balance-cock, the  bridge of the   tourbillon carriage, or the oscillating weight of the  Harmony   anniversary models.<br \/><strong><br \/>Harmony Ultra-Thin Grande Complication Chronograph <br \/>Caliber 3500 <br \/><br \/><\/strong>The flagship model of the new collection, presented in a 10-piece limited, numbered edition, the new Harmony Ultra-Thin Grande Complication Chronograph by Vacheron Constantin immediately makes its mark in the field of ultra-thin horology by setting a new world record with its self-winding movement measuring just 5.20 mm thick and its 8.40 mm cushion-shaped case. It took prodigious feats of miniaturisation to develop and ensure the faultless, high-precision operation of this elaborate construction within such a small space. It also required the skills of the most experienced watchmakers in the Manufacture to assemble and adjust to perfection the 459 parts of the new self-winding Vacheron Constantin Caliber 3500 \u2013 some of which, such as the tiny springs, measure just 3\/100ths of a millimetre. <br \/>\u00a0<br \/>For the first time in the range of Manufacture Vacheron Constantin calibers, this self-winding movement with its 51-hour power reserve is equipped with a remarkable peripheral oscillating weight. Mounted on ball bearings, this unusual construction provides a perfectly clear view of Caliber 3500, entirely hand-decorated in keeping with the noblest watchmaking traditions. This peripheral structure also serves to preserve the exceptional slimness of the world\u2019s thinnest self-winding split-seconds chronograph movement. To signal its membership of an exclusive series dedicated to the 260th anniversary of the Manufacture, the peripheral oscillating weight of the Harmony Ultra-Thin Grande Complication Chronograph by Vacheron Constantin bears the dedicated scrolling pattern specifically created by the brand\u2019s designers for this occasion. This unusual motif, also known as \u201cfleurisanne engraving\u201d is inspired by the arabesques adorning the balance-cock of the oldest pocket watch from the Maison, signed by Jean-Marc Constantin in 1755.\u00a0 <br \/>\u00a0<br \/>Equipped with a split-seconds function serving to time phenomena starting at the same time but of different durations, the new Harmony Ultra-Thin Grande Complication Chronograph by Vacheron Constantin is the slimmest in its category in terms of both its movement and its case. The first self-winding split-seconds Vacheron Constantin chronograph to bear the prestigious Hallmark of Geneva, this new in-house pays tribute to the aesthetic of the chronographs made for the brand in the 1920s, by reinterpreting the rounded shape and the interior angle bevelling of the bridges \u2013 that can only be done by hand \u2013 along with gold bushing and drop-shaped jewel surrounds. <br \/>\u00a0<br \/>Development work on Caliber 3500 began in 2008, aimed at developing a chronograph movement featuring a traditional kind of architecture, while benefiting from cutting-edge technologies in order to offer reliability, user friendliness and perfect visualisation of the movement aesthetic. This caliber benefits from the numerous advanced features designed by the Manufacture\u2019s development team, including the so-called \u201cfriction\u201d technique for the lateral coupling clutch, which serves to reduce a potential jerk of the hand when the chronograph starts running. Another particularly notable breakthrough is the blocking of the rotor when the barrel is sufficiently wound, thereby avoiding excessive tension in the winding spring. The creation of cone-shaped wheels improves the meshing of the wheels, thus giving the wearer the impression of softer, gentler winding. Moreover, the micro-technologies used for cutting the wheels have made it possible to create extremely close-set teeth to improve the engagement of the gear trains. The creation of an ultra-thin non-spherical differential has contributed to maintaining the power-reserve indication, without influencing the movement\u2019s thickness. Finally, the development of a \u201cdragging\u201d chronograph minutes indication reduces the loss in amplitude and thus improves precision.\u00a0 <br \/>\u00a0<br \/>Housed in a precious cushion-shaped case made of 950 platinum, Caliber 3500 deserved an exterior to match its excellence. The \u201cshape-in-a-shape\u201d case combining a curving case, a square waisted case middle and a circular bezel creates a sensation of slenderness, while demonstrating an entirely unique and impressive character. The hours, minutes, small seconds at 9 o\u2019clock and power reserve are clearly displayed on a luminous opaline silver-toned dial framed by a deep red tachometric scale.

• VACHERON CONSTANTIN
  
  THE VACHERON CONSTANTIN “HARMONY” COLLECTION AUTHENTIC WATCHMAKING SCULPTURE
  
  On the occasion of the 260th anniversary of its founding, the Manufacture Vacheron Constantin unveils the seven first models of a new collection called Harmony. Issued in limited editions, these eminently contemporary timepieces feature a new cushion shape and a design inspired by one of the brand’s first wristwatch chronographs introduced in 1928. At the heart of these generous cases with their reinvented aesthetic beat new calibers – entirely designed, developed and produced in-house – focused on monopusher chronographs. A first version equipped with a split-second function sets slimness records with its ultra-thin self-winding movement measuring just 5.20 mm thick, while a second model stages a fascinating tourbillon and the third variation is equipped – like the original – with a pulsometric scale. Representing elegant horological complications that are some of the most highly sought after and most complex to produce, the monopusher chrono-graph models are complemented by a ladies’ double-pusher chronograph. A trio of dual-time watches housing a new in-house movement rounds off this unusual range of timepieces. Like the other most recent creations from the Manufacture, these special editions bear the prestigious Hallmark of Geneva.
   
  Founded by the youthful Genevan master-watchmaker Jean-Marc Constantin in 1755, Vacheron Constantin is the world’s oldest watch manufacturer engaged in uninterrupted activity since its creation. On the occasion of its 260th anniversary, Vacheron Constantin is introducing the first exclusive models of a new collection. Named Harmony and featuring an entirely reinvented cushion shape, this eminently contemporary interpretation of horological excellence signed Vacheron Constantin draws inspiration from the architectural lines and distinctive design of the first wrist chronographs made by the Manufacture in the late 1920s. Through its perfectly balanced three-dimensional “shape-in-shape” approach, Vacheron Constantin once again demonstrates its expertise as a watchmaking sculptor. This is achieved through a sophisticated case construction dedicated to precision, readability and comfort on the wrist, while pervaded by a disarming apparent simplicity. Moreover, this new generous and boldly distinctive silhouette complements the existing range of round or tonneau-shaped cases characterising the classic collections by the Maison.
   
  The reinvented cushion shape 
  The seven first references in the Harmony collection, presented this year in a limited anniversary edition, are dedicated to chronograph and dual-time functions through four new calibers entirely designed and developed in-house, along with an evolved version of an existing chronograph movement. This sculptural collection intended to host innovative in-house developments displays a resolutely modern design, while the generous lines of its cushion-shaped case lend themselves to accommodating medium complication and grande complication calibers.
   
  Once again demonstrating the dual nature of its horological expertise, distinguished by the art of shapes dedicated to time measurement, Vacheron Constantin has devised an innovative construction of the cushion shape that has been part of its range for almost a century. A curved case middle, a square bezel and a round watch glass meet and mingle in an elegant reinterpretation of the monopusher chronograph with pulsometric scale presented by the Manufacture in 1928. While the inspiration derived from the original model is immediately perceptible, each detail has been infinitely rethought, right the way through to the specific ways that light reflects off the case, in order to offer a unique and unprecedented shape, combined with optimal comfort. In the same way, each element of the dial and hands inspired by the original watch face has been reinvented to guarantee perfect readability of the functions.
   
  The chronograph in the spotlight
  The in-house calibers housed in the Harmony collection feature major technical and aesthetic innovations. For this anniversary series preceding the launch of the full mainstream collection in 2016, Vacheron Constantin celebrates a complication that has enjoyed a key place among its creations since 1917: the chronograph. Interpreted in its most elegantly classical expression – the monopusher chronograph – this collection greatly prized among connoisseurs requires considerable patience, dexterity and experience on the part of the watchmaker who assembles it. Four first models in this new collections embody the expertise of the Manufacture in the measurement of short times: the world’s thinnest monopusher split-second chronograph, with its self-winding Caliber 3500 measuring just 5.20 mm thick: the monopusher tourbillon chronograph, driven by manual-winding Caliber 3200; the monopusher pulsimeter chronograph, with manual-winding Caliber 3300 – a variation directly inspired by the 1928 model; and finally, a double-pusher ladies’ chronograph powered by manual-winding Caliber 1142.
   
  New in-house calibers
  Stemming from seven years of research and development, the three new monopusher chronographs presented in the Harmony collection are driven by calibers entirely developed and produced within the Manufacture Vacheron Constantin, completely in keeping with its watchmaking heritage while benefiting from cutting-edge technologies. While the architecture of these movements reflects the traditional aesthetic of Haute Horlogerie chronographs and their classic column-wheel construction, the design of these new calibers enjoys the best of modern manufacturing processes providing a wealth of advancements in terms of materials, precision, functionality, aesthetics and user friendliness. Reflecting the same approach of combining tradition with state-of-the-art technologies, the development of self-winding Caliber 2640DT – which also began in 2008 – delivers a new addition to this innovative range of in-house horological complications by providing a dual-time display. Two elegant masculine models crafted in white or pink gold, as well as a diamond-set white gold feminine versions, are equipped with this useful complication featuring an elaborate mechanism enabling easy adjustment of all functions via the crown.
   
  More than ever, technical sophistication combined with a unique aesthetic are dedicated to differentiated time measurement through various new calibers and complications:
   
  • Time measured and sequenced: the chronograph and split-second chronograph
  • Time captured and simplified at a single press: the monopusher
  • Precise time: the tourbillon
  • Time linked to the heart: the pulsimeter
  • Offset time: dual time
   
  In keeping with the finest watchmaking traditions and like all Vacheron Constantin creations, these new calibers are adorned with remarkable finishing entirely performed by brilliantly skilled artisans. Mirror polishing, bevelling, circular graining and Côtes de Genève are merely the most notable examples of the countless finishes patiently applied to components that often remain hidden from sight. Stamped with the prestigious Hallmark of Geneva, they meet the numerous demanding criteria of this independent and sovereign label that is a guarantee of origin, of precision, of durability and of watchmaking expertise.
   
  In addition, so as to single out the seven inaugural timepieces in the Harmony collection, issued in limited editions, a scrolling motif inspired by the balance-cock on the oldest pocket watch belonging to the Maison and signed by Jean-Marc Constantin in 1755, variously adorns the oscillating weight, the chronograph bridge or the balance-cock of these models. Also known as “fleurisanne engraving”, this refined ornamentation is reserved for the Vacheron Constantin 260th anniversary special editions and a commemorative inscription is duly engraved on the back of these highly exclusive timepieces.
   
  A contemporary projection of the finest horological traditions
  The inspiration for the Harmony collection can be traced to a historical model with a distinctive character, equipped with an extremely elegant and sought-after complication: one of the first chronograph wristwatches introduced by Vacheron Constantin in 1928. This monopusher chronograph with a yellow gold cushion-shaped case was equipped with a 13-ligne caliber displaying a pulsometric scale around the rim of the white dial punctuated by leaf-type hands and painted Arabic numerals. Originally a medical instrument, the pulsimeter chronograph enabled doctors and nurses to take fast readings thanks to the chronograph hand showing the pulse rate after 30 beats on a graduated scale. When placed side by side, the chronograph and original version show undeniable similarities. The aesthetic reference is immediately apparent and the kinship is accentuated by the innate elegance of the monopusher mechanism. Driven by their extreme perfectionism, the designers and developers at Vacheron Constantin have nonetheless gone well beyond merely modernising a vintage model. Each detail, each line, each curve, each characteristic and each reflection has been rethought so as to offer a contemporary projection of Vacheron Constantin’s ancestral expertise. On both technical and aesthetic levels, this ultimate reinterpretation of the 1928 chronograph has given rise to an authentic work of art.
   
  The multiple facets of a horological work of art
  The traditional cushion shape is thus transfigured by a three-dimensional “shape in a shape” architecture, while the movement it houses is a distinctively Haute Horlogerie mechanism featuring a unique construction coupled with exceptional reliability and performances. This resolutely contemporary and sophisticated construction, combining a curved case middle, a square bezel and a round glass, highlights a silhouette graced with dynamic curves and multiple facets. Imbued with a blend of purity and equilibrium, the aesthetic of the case creates a perception of finesse in terms of its volumes, while the profile with its stretched lugs provides a flowing, continuous surface for the light to play over, yet without in any way being simplistic. This quest for perfect harmony in lines, curves, facets and reflections expresses the artistry deployed by Vacheron Constantin in creating horological sculptures destined to host finely crafted movements. A true virtuoso when it comes to shapes, the Manufacture excels in highlighting the most complex mechanisms through a unique aesthetic stemming from an authentic artistic approach. Designed to enhance the readability, the precision and the practical nature of the movement they house, these perfectly proportioned volumes provide a first-rate showcase for the Vacheron Constantin and serve to accommodate a wide variety of complications. Destined to become brand classics, the new timepieces in the Harmony collection are part of a modern and daring universe in which technique meets the art of shapes in a remarkable horological sculpture. 
  
  A face radiating supreme purity
  While the medium complication and grande complication calibers unveiled this year naturally deserved a case on a par with their inherent excellence, creating perfectly readable dials corresponds to the same standards of ultimate refinement. In this instance, the inspiration drawn from the 1928 chronograph gives rise to intense reinterpretation: each original characteristic is re-embodied in the most original possible contemporary expression. Designed with an admirable concern for details, the shapes of the numerals and letters as well as the colour choices were carefully thought through in order to perfect the limpid nature of a complex display and to reinforce its unique aesthetic. The elegance and sophistication of the monopusher chronograph are thus displayed with great distinction in a luminous silver-toned dial featuring painted Arabic numerals and slender leaf-type hands. Entirely redesigned and resized to compose an entirely original creation, the blue painted numerals of the Harmony collection give a unique smoothness to the dial – placed extremely close to the hands in a striking visual effect – along with incomparable legibility. While this reinterpretation preserves the original spirit and elegant classicism of the 1920s, it lends a unique personality to the new Vacheron Constantin line. Imbued with an entirely reinvented historical dimension, the “leaf” shape of the hands characterising the 1928 model also makes its first entrance in the current Vacheron Constantin collections. The slender, elongated shape ensures the excellent precision required by these elaborate movements, while the purity of their outlines radiates an exquisitely refined traditional charm. The delicately blued chronograph hands mark off the specific functions of short-time measurement, accentuating the clarity of the displays translating the intricate workings of such complex mechanisms. In a subtle contrast with the deep blue of the numerals and hands, the minute circle graduations, on which the pulsometric and tachometric scales appear in a vivid red, thereby reinforcing the excellent readability of these gracefully uncluttered dials.
   
  Horological sculpture: the art of shapes dedicated to the measurement of time
  With the 3500, 3200, 3300 and 1142 calibers, Vacheron Constantin pays tribute to the chronograph – a complication that has been a key part of its watchmaking heritage for a century already, since it was back in 1852 that Vacheron Constantin created its first pocket watches with an independent seconds hands on “medical chronographs” featuring a dedicated graduated scale on the dial. In 1873, the Manufacture created its first pocket chronograph, and in 1917, it miniaturised it to wristwatch size for the first time. These first models reflected the specific requirements of watch mechanisms capable of measuring short times with extreme precision. Thus, from an early phase in its history, the Vacheron Constantin Manufacture developed expertise in the development of highly technical complications and timepieces, capable of performing scrupulously accurate time measurements, resistant to extreme conditions or intended for scientific observations at sea on in the air. These capabilities are notably apparent in the number of orders for antimagnetic chronograph watches or chronometers that were met between 1880 and 1910. Such requests stemmed from doctors, military observatories, engineers or navies. Vacheron Constantin’s horological science has been gradually honed and extended throughout its history, and the art of “sculpting time” in order to meet highly demanding specific needs is admirably embodied in the Harmony collection.
   
  While the cushion shape was first introduced in the 1920s to showcase one of the brand’s chronographs, previously used in a pocket watch, this same approach has guided the creation of the new Harmony collection. Pervaded by a powerful sense of dynamism and modernity, the unique aesthetic of these new models is dedicated to serving the precision and readability of the elaborate functions. Its sophisticated construction raises Harmony to the rank of a horological sculpture, while the un-usual movements inside it offer a multi-facetted vision of time.
   
  Chronograph: tradition reinvented
  Composed of two Greek words – chronos and graphien – which together mean “writing time”, the chronograph is designed to measure short and medium-length events. Fulfilling one of humankind’s oldest dreams, that of mastering time, the chronograph evokes speed and power in the minds of collectors and connoisseurs of Haute Horlogerie. This has made it one of the most sought-aftercomplications since the birth of the mechanical watch in the 1980s. So as to provide a fresh demonstration of excellence in writing a new page in its history, the Manufacture Vacheron Constantin has chosen this complex and refined function to inaugurate the Harmony collection. From 2008 onwards, the Vacheron Constantin engineers, designers and watchmakers set to work, guided by the same spirit that inspired Jean-Marc Constantin in 1755 when he opened his workshop in the Saint-Gervais district of Geneva: developing the most accomplished timepieces, driven by the most daring techniques. From the production of the first watch bearing the signature of Jean-Marc Constantin to the launch of the Harmony collection, 260 years have elapsed, witnessing the birth of some of the world’s most complicated and sought-after chronographs, all bearing the stamp of Vacheron Constantin’s ancestral know-how. In 1917, the Geneva-based Manufacture presented its first wrist chronograph. Ever since, it has tireless perfected this demanding complication, in order to offers its owner the freedom to write his own time and to control it in a comfortable, elegant and assured manner.
   
  Technical and aesthetic innovations
  While the chronograph is a highly coveted complication that has appealed to connoisseurs around the world for almost two centuries, its production proves a highly complex process, due to the many mobile parts composing it. Thus, when the Vacheron Constantin research team began work seven years ago on creating a new chronograph movement, the aim was clear: to create a movement with a classic architecture, while making the most of the materials and technologies of contemporary watchmaking. To ensure its refined elegance and in tribute to the creations produced by the Manufacture in the 1920s and 1930s, it must have only one pusher. Yet behind the apparent simplicity of the chronograph lies a difficult complication calling for great dexterity and precision in order to master its adjustments and enable the owner to enjoy the inimitably smooth and comfortable feel of a single pusher. In the course of the development process, the objective became even more specific: the chronograph movement was to feature a traditional column wheel and a lateral coupling clutch, while incorporating highly ingenious advanced features such as the “dragging” minutes counter and the new “friction” technique for the lateral coupling clutch. The latter manages to address the problem that sometimes impairs the running of a chronograph: pressing the pusher tends to make the chronograph seconds hand give a slight jerk before starting to run. The chronograph was thus entirely redesigned in order to reduce and even eliminate this tiny jump.
   
  Pursuing the crucial goal of developing a perfectly functional, reliable and user-friendly caliber, the quest for perfection was carried right the way through to the smallest details, such as a cone-shaped gear between the winding pinion and the crown wheel in order to achieve pleasantly smooth, gentle winding. Moreover, these new movements also benefit from a cutting-edge technology that served to make an extremely precise wheel profile guaranteeing minimal clearance between the gears – with the teeth separated by barely 0.03 mm! Other technical and aesthetic achievements set the finishing touch to these new calibers combining beauty and technicality. Whether visible or concealed, these refined details embody the watchmaking art according to Vacheron Constantin, revealed in the chronograph gears shaped in the form of the Maltese cross, or the screw holding the column wheel and also adorned with the brand emblem.
   
  Haute Horlogerie finishing and anniversary decoration
  Like all creations by Vacheron Constantin and bearing the prestigious Hallmark of Geneva, the new calibers of the Harmony collection are adorned with the finest Haute Horlogerie finishing. Among these artisan-style finishes, the most remarkable of which are black or specular polishing, bevelling, circular-graining and Côtes de Genève. Entirely hand-crafted by specialised artisans, the decoration of all parts, including those invisible to the naked eye, requires not only a thorough learning process but also great dexterity and intent concentration. Driven by the constant concern for excellence and perfection that sets an authentic Haute Horlogerie apart from the rest, Vacheron Constantin masters more than a dozen different types of finishing.
   
  So as to further enhance the inherent distinction of the inaugural models in the Harmony collection – issued in limited series – and to ensure them a lasting place within this exceptional celebration of the history of the Manufacture, the Vacheron Constantin designers have created an exclusive movement decoration specifically dedicated to its 260th anniversary. The design team, which normally focuses in the watch exterior, thus had the privilege of dreaming up an original motif inspired by the arabesques that adorned the balance-cock of the oldest pocket watch belonging to the House and signed Jean-Marc Constantin in 1755. Also referred to as “fleurisanne engraving”, this decoration also appears on the balance-cock, the bridge of the tourbillon carriage, or the oscillating weight of the Harmony anniversary models.
  
  Harmony Ultra-Thin Grande Complication Chronograph
  Caliber 3500
  
  The flagship model of the new collection, presented in a 10-piece limited, numbered edition, the new Harmony Ultra-Thin Grande Complication Chronograph by Vacheron Constantin immediately makes its mark in the field of ultra-thin horology by setting a new world record with its self-winding movement measuring just 5.20 mm thick and its 8.40 mm cushion-shaped case. It took prodigious feats of miniaturisation to develop and ensure the faultless, high-precision operation of this elaborate construction within such a small space. It also required the skills of the most experienced watchmakers in the Manufacture to assemble and adjust to perfection the 459 parts of the new self-winding Vacheron Constantin Caliber 3500 – some of which, such as the tiny springs, measure just 3/100ths of a millimetre.
   
  For the first time in the range of Manufacture Vacheron Constantin calibers, this self-winding movement with its 51-hour power reserve is equipped with a remarkable peripheral oscillating weight. Mounted on ball bearings, this unusual construction provides a perfectly clear view of Caliber 3500, entirely hand-decorated in keeping with the noblest watchmaking traditions. This peripheral structure also serves to preserve the exceptional slimness of the world’s thinnest self-winding split-seconds chronograph movement. To signal its membership of an exclusive series dedicated to the 260th anniversary of the Manufacture, the peripheral oscillating weight of the Harmony Ultra-Thin Grande Complication Chronograph by Vacheron Constantin bears the dedicated scrolling pattern specifically created by the brand’s designers for this occasion. This unusual motif, also known as “fleurisanne engraving” is inspired by the arabesques adorning the balance-cock of the oldest pocket watch from the Maison, signed by Jean-Marc Constantin in 1755. 
   
  Equipped with a split-seconds function serving to time phenomena starting at the same time but of different durations, the new Harmony Ultra-Thin Grande Complication Chronograph by Vacheron Constantin is the slimmest in its category in terms of both its movement and its case. The first self-winding split-seconds Vacheron Constantin chronograph to bear the prestigious Hallmark of Geneva, this new in-house pays tribute to the aesthetic of the chronographs made for the brand in the 1920s, by reinterpreting the rounded shape and the interior angle bevelling of the bridges – that can only be done by hand – along with gold bushing and drop-shaped jewel surrounds.
   
  Development work on Caliber 3500 began in 2008, aimed at developing a chronograph movement featuring a traditional kind of architecture, while benefiting from cutting-edge technologies in order to offer reliability, user friendliness and perfect visualisation of the movement aesthetic. This caliber benefits from the numerous advanced features designed by the Manufacture’s development team, including the so-called “friction” technique for the lateral coupling clutch, which serves to reduce a potential jerk of the hand when the chronograph starts running. Another particularly notable breakthrough is the blocking of the rotor when the barrel is sufficiently wound, thereby avoiding excessive tension in the winding spring. The creation of cone-shaped wheels improves the meshing of the wheels, thus giving the wearer the impression of softer, gentler winding. Moreover, the micro-technologies used for cutting the wheels have made it possible to create extremely close-set teeth to improve the engagement of the gear trains. The creation of an ultra-thin non-spherical differential has contributed to maintaining the power-reserve indication, without influencing the movement’s thickness. Finally, the development of a “dragging” chronograph minutes indication reduces the loss in amplitude and thus improves precision. 
   
  Housed in a precious cushion-shaped case made of 950 platinum, Caliber 3500 deserved an exterior to match its excellence. The “shape-in-a-shape” case combining a curving case, a square waisted case middle and a circular bezel creates a sensation of slenderness, while demonstrating an entirely unique and impressive character. The hours, minutes, small seconds at 9 o’clock and power reserve are clearly displayed on a luminous opaline silver-toned dial framed by a deep red tachometric scale. The blue-painted Arabic numerals beautifully match the blued chronograph hands, while elegant leaf-type hands punctuate the hours and minutes.
   
  Inaugurating the Harmony collection in an outstandingly elegant manner, the new Ultra-Thin Grande Complication Chronograph by Vacheron Constantin expresses the full degree of mastery achieved by the Geneva Manufacture in the art of shapes dedicated to serving horological science successfully blending tradition with modernity.
