Jaeger-Le Coultre Master Ultra Thin Q114258J Watch

An elegant interpretation of one of watchmaking’s most demanding complications, the Master Ultra Thin Perpetual Calendar combines a refined 18ct pink gold case with a rich midnight-blue dial and an exceptionally slim profile. At 39 mm in diameter and just 9.2 mm thick, its polished case and elongated lugs give the watch a distinctly sophisticated presence. The dial balances applied hour markers and Dauphine hands with neatly arranged indications for the day, date, month, year and moon phase, creating an impressive level of information without compromising its understated dress-watch character. Powering the watch is Jaeger-LeCoultre’s in-house Calibre 868, an automatic movement measuring only 4.72 mm thick. With 330 components, 46 jewels and a 70-hour power reserve, it delivers the technical substance expected of a true manufacture perpetual calendar. The complication automatically accounts for the varying lengths of the months and leap years, requiring no correction until 2100. The movement is visible through the sapphire-crystal case back, while a blue alligator strap with quick-release technology and a pink gold pin buckle completes the presentation. With its combination of discreet proportions, precious-metal construction and sophisticated calendar mechanism, the Q114258J is a compelling choice for the collector seeking high complications in a refined, contemporary dress-watch format.
