Master Ultra Thin Moon 39

 
Three emblematic complications in a Fine Watchmaking line, Master Control by Jaeger-LeCoultre.
 
Checking the time in 24 time zones; the triumph of slenderness, finesse and precision; a perpetual calendar with a unique eight-day power reserve: these are the three emblematic horological complications celebrated by the Manufacture Jaeger-LeCoultre in paying homage to the noblest watchmaking traditions. Elegance and refinement are undoubtedly the watchwords of the models in the Master Control line with their classically understated shapes, breathtakingly beautiful dials… and their touch of originality that inevitably arouses special feelings for timepieces that any watchmaking devotee immediately senses have a soul of their very own

Master Ultra Thin Moon: technique and sophistication

No one element dominates the others and no characteristic is superfluous: minimalism is above all a question of equilibrium. Combining refinement, elegance and performance is a given for the Manufacture Jaeger-LeCoultre, which played a pioneering role in the quest for slenderness. At just 4.9 mm thick, the new ultra-thin automatic Jaeger-LeCoultre Calibre 925 movement associates the indications that are indispensable in an accurate watch – hours, minutes and seconds – with two additional functions meeting different and complementary demands: the date and moon phases. Both appear on a single counter in the sunray brushed dial centre, with a delicately shaped arrow pointing to the date. The Master Ultra Thin Moon, a model radiating absolute stylistic purity, is as much a tribute to the splendid tradition of round watches that have forged the reputation of the Manufacture Jaeger-LeCoultre, as a celebration of horological research in the history of ultra-thin movements.
 
Tried and tested precision and reliability: Manufacture Jaeger-LeCoultre’s unique 1000 Hours Control

However elegant and refined they may be, timekeepers are worthy of their name – and indeed of the prestigious Jaeger-LeCoultre signature adorning their dial – only if they meet stringent demands in terms of exactness and reliability. The Manufacture has developed a series of merciless tests that submit newly completed watches to severe trials. For almost twenty years now, none of them has left the workshops of the Grande Maison without first having valiantly demonstrated its ability to surmount the difficulties of an adventurous existence. Their rating precision is tested in six positions, at rest and in motion, while the prophylactic administration of calculated shocks proves their sturdiness, and their water resistance is verified under 5-bar pressure. After 1000 hours of constant controls, each watch is finally authorised to join the proud cohort of representatives of the Master Control line, and to set off towards the encounter with its future owner
