MASTER ULTRA THIN POWER RESERVE, Q1378421

Faithful to the emblematic watchmaking spirit of the collection, the Master Ultra Thin Power Reserve watch epitomises the subtle blend of technical prowess and aesthetic refinement. In this understated stainless steel version, the case with its curved lugs features a dial with unique architecture - a signature element of the model. The elongated hour-markers, double polished and satin-finished Dauphine hands, Jaeger-LeCoultre applied logo, opaline counters and minute track dots stand out harmoniously against the silver sunrayed background. The in-house Calibre 938 lies at the heart of the watch, equipped with a silicon escapement offering a power reserve of 70 hours, providing real comfort: there is no need to wind the watch, even after a whole weekend without wearing it. Beneath its slender case, which reflects the watchmaking expertise of La Grande Maison, this high-precision watch defies times with as much boldness as sophistication.
