Looking to the future, the brand has rethought the perpetual calendar, which mechanically reproduces the movement of the celestial bodies, with ergonomics at its heart to adapt to evolving lifestyles and open up new technical and design avenues. The result? An intuitive complication that revolutionises the perpetual calendar experience while improving legibility. This new movement makes its debut on a 41 mm Code 11.59 by Audemars Piguet in 18-carat white gold, on two 41 mm Royal Oak models in a choice of stainless steel or 18-carat sand gold, and on three corresponding \u201canniversary\u201d limited editions of 150 pieces, each featuring subtle aesthetic details that pay homage to the Manufacture\u2019s 150 years of uncompromising craftsmanship. Five years of development went into the creation of this horological feat, which is protected by five patents and offers new creative horizons.<\/p>\n<p>\u201cAstronomical watches have shaped Audemars Piguet\u2019s world since 1875. To celebrate 150 years of remarkable craftsmanship and innovation, our watchmakers and engineers have put the user and their experience at the forefront of their agenda to create a new perpetual calendar that is both intuitive and easy to use. To this end, they invented a one-of-a-kind system that makes all corrections possible only using the crown \u2013 a true mechanical breakthrough that required the complete redesign of the movement. The magic lies in the watch\u2019s seamless blend of technical complexity and simplicity of use.\u201d<\/p>\n<p><strong>Ilaria Resta<\/strong><\/p>\n<p><strong>Chief Executive Officer, Audemars Piguet<\/strong><\/p>\n<p><\/p>\n<p><strong>A COMPLICATION ROOTED IN THE UNIVERSE<\/strong><\/p>\n<p>Since ancient times, the sun has been our daily timekeeper, while the moon, observable stars and constellations have been our calendars. The rotation of these celestial bodies has served as the basis for the development of timekeeping instruments. Over time, horological devices evolved from sundials and water clocks to highly complicated mechanical clocks and portable watches.<\/p>\n<p>The perpetual calendar saw the light of day in its earliest form in the 18th century. This astronomical complication,<strong> <\/strong>one of the most complex calendar watches in existence today, has a mechanical memory capable of mapping 48-month time cycles, automatically adjusting the varying number of days in each month, even during leap years. This complex mechanism requires manual intervention only once every 100 years to keep it in sync with our solar time!1 Rooted in history and nature, this classic complication has captured the imagination of watchmakers for centuries, spurring them to develop ever-more complicated mechanisms to bring us closer to the universe and its cyclic rhythms.<\/p>\n<p><strong>ERGONOMIC AND INTUITIVE ALL-IN-ONE CROWN<\/strong><\/p>\n<p>Building on its heritage and past developments while looking to the future, Audemars Piguet has reimagined the perpetual calendar mechanism with ergonomics in mind to adapt this classic complication to an ever-more flexible lifestyle.<\/p>\n<p>Traditional perpetual calendar wristwatches are usually equipped with correctors inserted in the side of the case, which are activated by using a small tool to adjust the various subdials. This age-old system can make it cumbersome to set the watch, especially when left unwound for some time. To enhance user\u2019s experience and streamline the design of the case, AP\u2019s engineers have developed an easier and more intuitive correction system entirely controlled via the crown, to make this high complication adjustable anywhere without tools and without risk of damage.<\/p>\n<p>The new crown incorporates four different positions. The first enables to wind the watch clockwise. Pulling the crown out one step (position 2) allows to set the date clockwise and to adjust the month and the leap year in the opposite direction. By pulling the crown out again (position 3), the user can set the time bidirectionally. The last position is reached by pushing the crown back one step (position 2\u2019) to set the day and week clockwise and the moon phases counterclockwise.<\/p>\n<p>The simplicity of the new crown correction conceals, however, a complex mechanism driven by an innovative lever and wandering wheels system that meshes with the different calendar wheels in the 2 and 2\u2019 positions. This innovation is protected by two patents: one for the crown correction system with a 2\u2019 position and one for the month and date correction via the crown.<\/p>\n<p><strong>A DIAL COMBINING LEGIBILITY WITH AESTHETIC HARMONY<\/strong><\/p>\n<p>The dial and subdials have been rearranged to enhance legibility, symmetry and aesthetic harmony. The dial now features a European date display, with the day at 9 o\u2019clock, the date at 12 and the month at 3 o\u2019clock. The week numbers are printed on the inner bezel as for previous perpetual calendar models. However, it is now the first week of the year (\u201c1\u201d) that appears at 12 o\u2019clock (instead of week 52). In the same logic, \u201cMonday\u201d and \u201c1\u201d have been aligned at 12 o\u2019clock in their respective subdial to mark the start of the week and the first day of the month. The dial also features a patented progressive step for the date display at 12 o\u2019clock. The AP teams developed a date wheel with 31 custom-made teeth, the size of which varies to adapt to the width of the digits and enhance readability.<\/p>\n<p>To achieve perfect symmetry with the subdial at 3 o\u2019clock, which indicates the month and leap year, a 24-hour indicator has been inserted in the day subdial at 9 o\u2019clock. In addition, a no-correction zone is marked in red between 21 h and 3 h to show when the watch cannot be set. However, if the user attempts to set the watch during this time, the date might not be corrected, but there is no risk of damaging the movement in the process.<\/p>\n<p>The moon phase, which displays a realistic depiction of the moon based on a NASA photograph, remains at 6 o\u2019clock as for previous references. However, the full moon is now centred on the 12 o\u2019clock axis to strengthen the dial\u2019s overall harmony.<\/p>\n<p><strong>A CALIBRE BLENDING TRADITION WITH INNOVATION<\/strong><\/p>\n<p>Audemars Piguet\u2019s new in-house perpetual calendar movement combines state-of-the-art R&D technology with age-old horological expertise. Calibre 7138 automatically takes into account the number of days in the month and correctly displays the date and week even in leap years. Assuming the watch is kept fully wound, the date will not require manual correction until the year 2100, when it will need to be adjusted to stay in line with the Gregorian calendar.3 With selfwinding Calibre 7121 as its base, it beats at a frequency of 4 Hz (28,800 vph) and offers a power reserve of minimum 55 hours. Calibre 7138 also builds on the patented innovations of Calibre 5133 launched in 2018 with the Royal Oak Selfwinding Perpetual Calendar Ultra- Thin RD#2, which incorporated all perpetual calendar functions in one single layer within the movement. The end-of-month cam is similarly integrated with the date wheel, while the month cam is combined with the month wheel. Crown corrections form a second layer, enabling the movement to keep a thin 4.1 mm profile. Calibre 7138 is decorated with refined Haute Horlogerie decorations, including C\u00f4tes de Gen\u00e8ve, satin-brushing, circular graining and satin, snailing as well as chamfering, all visible on the caseback side.<\/p>\n<p>\u201cCalibre 7138 represents a major innovation in the design of perpetual calendars.<\/p>\n<p>By placing ergonomics at the heart of our research and development, we have created a unique correction mechanism that allows all adjustments to be made via the crown.<\/p>\n<p>In addition to making this high complication easy to use, we also worked on the overall aesthetics to combine high legibility with timeless refinement.\u201d<\/p>\n<p><strong>Lucas Raggi<\/strong><\/p>\n<p><strong>Research and Development Director, Audemars Piguet<\/strong><\/p>\n<p><\/p>\n<p><strong>ONE MOVEMENT THREE REFINED AESTHETICS<\/strong><\/p>\n<p>Calibre 7138 makes its debut with one Code 11.59 by Audemars Piguet and two Royal Oak models, all available in 41 mm. The absence of correctors on the side of the case reinforces the refinement of the three models as well as their water resistance, which has been increased to 50 m for the Royal Oak models and 30 m for the Code 11.59 by Audemars Piguet compared to the previous perpetual calendar models offered in the two collections (20 m). The new 41 mm Code 11.59 by Audemars Piguet timepiece continues the collection\u2019s seamless blend of technical modernity and ancestral craftsmanship. It features an 18-carat white gold case, whose multi-layered architecture is highlighted by the Manufacture\u2019s alternation of satin- brushing and polished chamfers that play with the light.<\/p>\n<p>It is enhanced by the collection\u2019s signature embossed dial in smoked blue PVD shades. The pattern is made up of concentric circles that ripple outwards from the centre of the dial and is decorated with hundreds of tiny holes that give it light, depth and character. This motif, which made its debut in the collection in 2023, was created in collaboration with Swiss guilloch\u00e9 artisan Yann von Kaenel, who hand-engraved the basic stamps. The dial is complemented by 18-carat white gold luminescent hands, white gold hour- markers and white calendar indications for an elegant two-tone design. The timepiece is fitted on a blue rubber-coated strap with calfskin lining matching the hue of the dial, decorated with a textile motif for a contemporary twist.<\/p>\n<p>The first Royal Oak model also offers a two-tone aesthetic. It combines a stainless steel case and bracelet with a blue PVD Grande Tapisserie dial with matching subdials and inner bezel. The dial is enhanced by 18-carat white gold hands and hour-markers, all filled with luminescent material. White calendar indications on the inner bezel and subdials add the finishing touch.<\/p>\n<p>The second Royal Oak timepiece presents a contemporary monochrome aesthetic with unique light effects. The case and bracelet are crafted in 18-carat sand gold, a precious alloy combining gold with copper and palladium, introduced in the Royal Oak collection in 2024. Hovering between white and pink gold, its colour changes according to the light, giving it a warm appearance. The Manufacture\u2019s trademark satin-finishing and polished chamfers on the bracelet and case accentuate the material\u2019s chromatic variation. The timepiece is adorned with a Grande Tapisserie dial, subdials and inner bezel, all in the same sand gold shade, obtained by galvanic treatment. The 18-carat white gold hands and hour-markers with luminescent material add a touch of refinement, while the black calendar indications printed on the subdials and inner bezel provide a subtle contrast. The three models have a sapphire caseback that reveals the refined aesthetic of Calibre 7138. The openworked oscillating weight in 22-carat pink gold and the barrel bridge visible from 12 to 3 o\u2019clock stand out against the other rhodium- toned components of the movement.<\/p>\n<p><strong>THREE \u201cANNIVERSARY\u201d LIMITED EDITIONS<\/strong><\/p>\n<p>To celebrate the Manufacture\u2019s 150 years, the three models presented above are also available in a limited \u201canniversary\u201d edition of 150 pieces each.

DESCRIPTION
A NEW GENERATION OF PERPETUAL CALENDAR MOVEMENT
ERGONOMICS MEETS PERFORMANCE IN AUDEMARS PIGUET’S NEW PERPETUAL CALENDAR
To mark the beginning of its 150th anniversary celebrations, Swiss Haute Horlogerie manufacturer Audemars Piguet is delighted to unveil a new generation of selfwinding perpetual calendar movement, Calibre 7138, which for the first time ever, enhances user comfort by making the corrections of all functions possible via its “all-in-one” crown. Looking to the future, the brand has rethought the perpetual calendar, which mechanically reproduces the movement of the celestial bodies, with ergonomics at its heart to adapt to evolving lifestyles and open up new technical and design avenues. The result? An intuitive complication that revolutionises the perpetual calendar experience while improving legibility. This new movement makes its debut on a 41 mm Code 11.59 by Audemars Piguet in 18-carat white gold, on two 41 mm Royal Oak models in a choice of stainless steel or 18-carat sand gold, and on three corresponding “anniversary” limited editions of 150 pieces, each featuring subtle aesthetic details that pay homage to the Manufacture’s 150 years of uncompromising craftsmanship. Five years of development went into the creation of this horological feat, which is protected by five patents and offers new creative horizons.
“Astronomical watches have shaped Audemars Piguet’s world since 1875. To celebrate 150 years of remarkable craftsmanship and innovation, our watchmakers and engineers have put the user and their experience at the forefront of their agenda to create a new perpetual calendar that is both intuitive and easy to use. To this end, they invented a one-of-a-kind system that makes all corrections possible only using the crown – a true mechanical breakthrough that required the complete redesign of the movement. The magic lies in the watch’s seamless blend of technical complexity and simplicity of use.”
Ilaria Resta
Chief Executive Officer, Audemars Piguet
A COMPLICATION ROOTED IN THE UNIVERSE
Since ancient times, the sun has been our daily timekeeper, while the moon, observable stars and constellations have been our calendars. The rotation of these celestial bodies has served as the basis for the development of timekeeping instruments. Over time, horological devices evolved from sundials and water clocks to highly complicated mechanical clocks and portable watches.
The perpetual calendar saw the light of day in its earliest form in the 18th century. This astronomical complication, one of the most complex calendar watches in existence today, has a mechanical memory capable of mapping 48-month time cycles, automatically adjusting the varying number of days in each month, even during leap years. This complex mechanism requires manual intervention only once every 100 years to keep it in sync with our solar time!1 Rooted in history and nature, this classic complication has captured the imagination of watchmakers for centuries, spurring them to develop ever-more complicated mechanisms to bring us closer to the universe and its cyclic rhythms.
ERGONOMIC AND INTUITIVE ALL-IN-ONE CROWN
Building on its heritage and past developments while looking to the future, Audemars Piguet has reimagined the perpetual calendar mechanism with ergonomics in mind to adapt this classic complication to an ever-more flexible lifestyle.
Traditional perpetual calendar wristwatches are usually equipped with correctors inserted in the side of the case, which are activated by using a small tool to adjust the various subdials. This age-old system can make it cumbersome to set the watch, especially when left unwound for some time. To enhance user’s experience and streamline the design of the case, AP’s engineers have developed an easier and more intuitive correction system entirely controlled via the crown, to make this high complication adjustable anywhere without tools and without risk of damage.
The new crown incorporates four different positions. The first enables to wind the watch clockwise. Pulling the crown out one step (position 2) allows to set the date clockwise and to adjust the month and the leap year in the opposite direction. By pulling the crown out again (position 3), the user can set the time bidirectionally. The last position is reached by pushing the crown back one step (position 2’) to set the day and week clockwise and the moon phases counterclockwise.
The simplicity of the new crown correction conceals, however, a complex mechanism driven by an innovative lever and wandering wheels system that meshes with the different calendar wheels in the 2 and 2’ positions. This innovation is protected by two patents: one for the crown correction system with a 2’ position and one for the month and date correction via the crown.
A DIAL COMBINING LEGIBILITY WITH AESTHETIC HARMONY
The dial and subdials have been rearranged to enhance legibility, symmetry and aesthetic harmony. The dial now features a European date display, with the day at 9 o’clock, the date at 12 and the month at 3 o’clock. The week numbers are printed on the inner bezel as for previous perpetual calendar models. However, it is now the first week of the year (“1”) that appears at 12 o’clock (instead of week 52). In the same logic, “Monday” and “1” have been aligned at 12 o’clock in their respective subdial to mark the start of the week and the first day of the month. The dial also features a patented progressive step for the date display at 12 o’clock. The AP teams developed a date wheel with 31 custom-made teeth, the size of which varies to adapt to the width of the digits and enhance readability.
To achieve perfect symmetry with the subdial at 3 o’clock, which indicates the month and leap year, a 24-hour indicator has been inserted in the day subdial at 9 o’clock. In addition, a no-correction zone is marked in red between 21 h and 3 h to show when the watch cannot be set. However, if the user attempts to set the watch during this time, the date might not be corrected, but there is no risk of damaging the movement in the process.
The moon phase, which displays a realistic depiction of the moon based on a NASA photograph, remains at 6 o’clock as for previous references. However, the full moon is now centred on the 12 o’clock axis to strengthen the dial’s overall harmony.
A CALIBRE BLENDING TRADITION WITH INNOVATION
Audemars Piguet’s new in-house perpetual calendar movement combines state-of-the-art R&D technology with age-old horological expertise. Calibre 7138 automatically takes into account the number of days in the month and correctly displays the date and week even in leap years. Assuming the watch is kept fully wound, the date will not require manual correction until the year 2100, when it will need to be adjusted to stay in line with the Gregorian calendar.3 With selfwinding Calibre 7121 as its base, it beats at a frequency of 4 Hz (28,800 vph) and offers a power reserve of minimum 55 hours. Calibre 7138 also builds on the patented innovations of Calibre 5133 launched in 2018 with the Royal Oak Selfwinding Perpetual Calendar Ultra- Thin RD#2, which incorporated all perpetual calendar functions in one single layer within the movement. The end-of-month cam is similarly integrated with the date wheel, while the month cam is combined with the month wheel. Crown corrections form a second layer, enabling the movement to keep a thin 4.1 mm profile. Calibre 7138 is decorated with refined Haute Horlogerie decorations, including Côtes de Genève, satin-brushing, circular graining and satin, snailing as well as chamfering, all visible on the caseback side.
“Calibre 7138 represents a major innovation in the design of perpetual calendars.
By placing ergonomics at the heart of our research and development, we have created a unique correction mechanism that allows all adjustments to be made via the crown.
In addition to making this high complication easy to use, we also worked on the overall aesthetics to combine high legibility with timeless refinement.”
Lucas Raggi
Research and Development Director, Audemars Piguet
ONE MOVEMENT THREE REFINED AESTHETICS
Calibre 7138 makes its debut with one Code 11.59 by Audemars Piguet and two Royal Oak models, all available in 41 mm. The absence of correctors on the side of the case reinforces the refinement of the three models as well as their water resistance, which has been increased to 50 m for the Royal Oak models and 30 m for the Code 11.59 by Audemars Piguet compared to the previous perpetual calendar models offered in the two collections (20 m). The new 41 mm Code 11.59 by Audemars Piguet timepiece continues the collection’s seamless blend of technical modernity and ancestral craftsmanship. It features an 18-carat white gold case, whose multi-layered architecture is highlighted by the Manufacture’s alternation of satin- brushing and polished chamfers that play with the light.
It is enhanced by the collection’s signature embossed dial in smoked blue PVD shades. The pattern is made up of concentric circles that ripple outwards from the centre of the dial and is decorated with hundreds of tiny holes that give it light, depth and character. This motif, which made its debut in the collection in 2023, was created in collaboration with Swiss guilloché artisan Yann von Kaenel, who hand-engraved the basic stamps. The dial is complemented by 18-carat white gold luminescent hands, white gold hour- markers and white calendar indications for an elegant two-tone design. The timepiece is fitted on a blue rubber-coated strap with calfskin lining matching the hue of the dial, decorated with a textile motif for a contemporary twist.
The first Royal Oak model also offers a two-tone aesthetic. It combines a stainless steel case and bracelet with a blue PVD Grande Tapisserie dial with matching subdials and inner bezel. The dial is enhanced by 18-carat white gold hands and hour-markers, all filled with luminescent material. White calendar indications on the inner bezel and subdials add the finishing touch.
The second Royal Oak timepiece presents a contemporary monochrome aesthetic with unique light effects. The case and bracelet are crafted in 18-carat sand gold, a precious alloy combining gold with copper and palladium, introduced in the Royal Oak collection in 2024. Hovering between white and pink gold, its colour changes according to the light, giving it a warm appearance. The Manufacture’s trademark satin-finishing and polished chamfers on the bracelet and case accentuate the material’s chromatic variation. The timepiece is adorned with a Grande Tapisserie dial, subdials and inner bezel, all in the same sand gold shade, obtained by galvanic treatment. The 18-carat white gold hands and hour-markers with luminescent material add a touch of refinement, while the black calendar indications printed on the subdials and inner bezel provide a subtle contrast. The three models have a sapphire caseback that reveals the refined aesthetic of Calibre 7138. The openworked oscillating weight in 22-carat pink gold and the barrel bridge visible from 12 to 3 o’clock stand out against the other rhodium- toned components of the movement.
THREE “ANNIVERSARY” LIMITED EDITIONS
To celebrate the Manufacture’s 150 years, the three models presented above are also available in a limited “anniversary” edition of 150 pieces each. While their aesthetics are identical to those of the collection models, the three limited editions feature subtle design codes specially conceived for the celebration.
These include a vintage “Audemars Piguet” signature inspired by historical documents, inserted in the moon- phase subdial at 6 o’clock. The three limited editions also incorporate two additional engravings on the sapphire caseback frame: the “150” logo, created for the occasion, and “1 of 150 pieces.”
“Astronomy is the mother of watchmaking. The history of time measurement began with the observation of the sky and the development of calendars to regulate our societies in days, months and years. Calendar watches have evolved over time to capture the cycles of celestial bodies with a combination of small cams and gears. Among them, the perpetual calendar – one of the most complex in this category – is like a small mechanical computer on the wrist capable of keeping the date correct for an entire century.
Perpetual calendars have marked the history of Audemars Piguet since 1875.”

To mark the beginning of its 150th anniversary celebrations, Swiss Haute Horlogerie manufacturer Audemars Piguet is delighted to unveil a new generation of selfwinding perpetual calendar movement, Calibre 7138, which for the first time ever, enhances user comfort by making the corrections of all functions possible via its “all-in-one” crown. Looking to the future, the brand has rethought the perpetual calendar, which mechanically reproduces the movement of the celestial bodies, with ergonomics at its heart to adapt to evolving lifestyles and open up new technical and design avenues. The result? An intuitive complication that revolutionises the perpetual calendar experience while improving legibility. This new movement makes its debut on a 41 mm Code 11.59 by Audemars Piguet in 18-carat white gold, on two 41 mm Royal Oak models in a choice of stainless steel or 18-carat sand gold, and on three corresponding “anniversary” limited editions of 150 pieces, each featuring subtle aesthetic details that pay homage to the Manufacture’s 150 years of uncompromising craftsmanship. Five years of development went into the creation of this horological feat, which is protected by five patents and offers new creative horizons.
“Astronomical watches have shaped Audemars Piguet’s world since 1875. To celebrate 150 years of remarkable craftsmanship and innovation, our watchmakers and engineers have put the user and their experience at the forefront of their agenda to create a new perpetual calendar that is both intuitive and easy to use. To this end, they invented a one-of-a-kind system that makes all corrections possible only using the crown – a true mechanical breakthrough that required the complete redesign of the movement. The magic lies in the watch’s seamless blend of technical complexity and simplicity of use.”

A COMPLICATION ROOTED IN THE UNIVERSE
Since ancient times, the sun has been our daily timekeeper, while the moon, observable stars and constellations have been our calendars. The rotation of these celestial bodies has served as the basis for the development of timekeeping instruments. Over time, horological devices evolved from sundials and water clocks to highly complicated mechanical clocks and portable watches.
The perpetual calendar saw the light of day in its earliest form in the 18th century. This astronomical complication, one of the most complex calendar watches in existence today, has a mechanical memory capable of mapping 48-month time cycles, automatically adjusting the varying number of days in each month, even during leap years. This complex mechanism requires manual intervention only once every 100 years to keep it in sync with our solar time!1 Rooted in history and nature, this classic complication has captured the imagination of watchmakers for centuries, spurring them to develop ever-more complicated mechanisms to bring us closer to the universe and its cyclic rhythms.
ERGONOMIC AND INTUITIVE ALL-IN-ONE CROWN
Building on its heritage and past developments while looking to the future, Audemars Piguet has reimagined the perpetual calendar mechanism with ergonomics in mind to adapt this classic complication to an ever-more flexible lifestyle.
Traditional perpetual calendar wristwatches are usually equipped with correctors inserted in the side of the case, which are activated by using a small tool to adjust the various subdials. This age-old system can make it cumbersome to set the watch, especially when left unwound for some time. To enhance user’s experience and streamline the design of the case, AP’s engineers have developed an easier and more intuitive correction system entirely controlled via the crown, to make this high complication adjustable anywhere without tools and without risk of damage.
The new crown incorporates four different positions. The first enables to wind the watch clockwise. Pulling the crown out one step (position 2) allows to set the date clockwise and to adjust the month and the leap year in the opposite direction. By pulling the crown out again (position 3), the user can set the time bidirectionally. The last position is reached by pushing the crown back one step (position 2’) to set the day and week clockwise and the moon phases counterclockwise.
The simplicity of the new crown correction conceals, however, a complex mechanism driven by an innovative lever and wandering wheels system that meshes with the different calendar wheels in the 2 and 2’ positions. This innovation is protected by two patents: one for the crown correction system with a 2’ position and one for the month and date correction via the crown.
A DIAL COMBINING LEGIBILITY WITH AESTHETIC HARMONY
The dial and subdials have been rearranged to enhance legibility, symmetry and aesthetic harmony. The dial now features a European date display, with the day at 9 o’clock, the date at 12 and the month at 3 o’clock. The week numbers are printed on the inner bezel as for previous perpetual calendar models. However, it is now the first week of the year (“1”) that appears at 12 o’clock (instead of week 52). In the same logic, “Monday” and “1” have been aligned at 12 o’clock in their respective subdial to mark the start of the week and the first day of the month. The dial also features a patented progressive step for the date display at 12 o’clock. The AP teams developed a date wheel with 31 custom-made teeth, the size of which varies to adapt to the width of the digits and enhance readability.
To achieve perfect symmetry with the subdial at 3 o’clock, which indicates the month and leap year, a 24-hour indicator has been inserted in the day subdial at 9 o’clock. In addition, a no-correction zone is marked in red between 21 h and 3 h to show when the watch cannot be set. However, if the user attempts to set the watch during this time, the date might not be corrected, but there is no risk of damaging the movement in the process.
The moon phase, which displays a realistic depiction of the moon based on a NASA photograph, remains at 6 o’clock as for previous references. However, the full moon is now centred on the 12 o’clock axis to strengthen the dial’s overall harmony.
A CALIBRE BLENDING TRADITION WITH INNOVATION
Audemars Piguet’s new in-house perpetual calendar movement combines state-of-the-art R&D technology with age-old horological expertise. Calibre 7138 automatically takes into account the number of days in the month and correctly displays the date and week even in leap years. Assuming the watch is kept fully wound, the date will not require manual correction until the year 2100, when it will need to be adjusted to stay in line with the Gregorian calendar.3 With selfwinding Calibre 7121 as its base, it beats at a frequency of 4 Hz (28,800 vph) and offers a power reserve of minimum 55 hours. Calibre 7138 also builds on the patented innovations of Calibre 5133 launched in 2018 with the Royal Oak Selfwinding Perpetual Calendar Ultra- Thin RD#2, which incorporated all perpetual calendar functions in one single layer within the movement. The end-of-month cam is similarly integrated with the date wheel, while the month cam is combined with the month wheel. Crown corrections form a second layer, enabling the movement to keep a thin 4.1 mm profile. Calibre 7138 is decorated with refined Haute Horlogerie decorations, including Côtes de Genève, satin-brushing, circular graining and satin, snailing as well as chamfering, all visible on the caseback side.
“Calibre 7138 represents a major innovation in the design of perpetual calendars.
By placing ergonomics at the heart of our research and development, we have created a unique correction mechanism that allows all adjustments to be made via the crown.
In addition to making this high complication easy to use, we also worked on the overall aesthetics to combine high legibility with timeless refinement.”

ONE MOVEMENT THREE REFINED AESTHETICS
Calibre 7138 makes its debut with one Code 11.59 by Audemars Piguet and two Royal Oak models, all available in 41 mm. The absence of correctors on the side of the case reinforces the refinement of the three models as well as their water resistance, which has been increased to 50 m for the Royal Oak models and 30 m for the Code 11.59 by Audemars Piguet compared to the previous perpetual calendar models offered in the two collections (20 m). The new 41 mm Code 11.59 by Audemars Piguet timepiece continues the collection’s seamless blend of technical modernity and ancestral craftsmanship. It features an 18-carat white gold case, whose multi-layered architecture is highlighted by the Manufacture’s alternation of satin- brushing and polished chamfers that play with the light.
It is enhanced by the collection’s signature embossed dial in smoked blue PVD shades. The pattern is made up of concentric circles that ripple outwards from the centre of the dial and is decorated with hundreds of tiny holes that give it light, depth and character. This motif, which made its debut in the collection in 2023, was created in collaboration with Swiss guilloché artisan Yann von Kaenel, who hand-engraved the basic stamps. The dial is complemented by 18-carat white gold luminescent hands, white gold hour- markers and white calendar indications for an elegant two-tone design. The timepiece is fitted on a blue rubber-coated strap with calfskin lining matching the hue of the dial, decorated with a textile motif for a contemporary twist.
The first Royal Oak model also offers a two-tone aesthetic. It combines a stainless steel case and bracelet with a blue PVD Grande Tapisserie dial with matching subdials and inner bezel. The dial is enhanced by 18-carat white gold hands and hour-markers, all filled with luminescent material. White calendar indications on the inner bezel and subdials add the finishing touch.
The second Royal Oak timepiece presents a contemporary monochrome aesthetic with unique light effects. The case and bracelet are crafted in 18-carat sand gold, a precious alloy combining gold with copper and palladium, introduced in the Royal Oak collection in 2024. Hovering between white and pink gold, its colour changes according to the light, giving it a warm appearance. The Manufacture’s trademark satin-finishing and polished chamfers on the bracelet and case accentuate the material’s chromatic variation. The timepiece is adorned with a Grande Tapisserie dial, subdials and inner bezel, all in the same sand gold shade, obtained by galvanic treatment. The 18-carat white gold hands and hour-markers with luminescent material add a touch of refinement, while the black calendar indications printed on the subdials and inner bezel provide a subtle contrast. The three models have a sapphire caseback that reveals the refined aesthetic of Calibre 7138. The openworked oscillating weight in 22-carat pink gold and the barrel bridge visible from 12 to 3 o’clock stand out against the other rhodium- toned components of the movement.
THREE “ANNIVERSARY” LIMITED EDITIONS
To celebrate the Manufacture’s 150 years, the three models presented above are also available in a limited “anniversary” edition of 150 pieces each. While their aesthetics are identical to those of the collection models, the three limited editions feature subtle design codes specially conceived for the celebration.
These include a vintage “Audemars Piguet” signature inspired by historical documents, inserted in the moon- phase subdial at 6 o’clock. The three limited editions also incorporate two additional engravings on the sapphire caseback frame: the “150” logo, created for the occasion, and “1 of 150 pieces.”
“Astronomy is the mother of watchmaking. The history of time measurement began with the observation of the sky and the development of calendars to regulate our societies in days, months and years. Calendar watches have evolved over time to capture the cycles of celestial bodies with a combination of small cams and gears. Among them, the perpetual calendar – one of the most complex in this category – is like a small mechanical computer on the wrist capable of keeping the date correct for an entire century.
Perpetual calendars have marked the history of Audemars Piguet since 1875.”
