Jaeger-LeCoultre Master Ultra Thin Moon 39 | Black Dial | Ref. Q1368470

The Story

The Jaeger-LeCoultre Master Ultra Thin Moon is the quintessential modern dress watch. At a perfectly balanced 39mm, it combines the technical prowess of the "Watchmaker of Watchmakers" with an aesthetic of pure, understated luxury. The deep black sunray dial serves as a dramatic canvas for the high-polish moonphase display at 6 o'clock, which also houses the pointer date indicator. Slim, sharp, and mechanically superior, this is a timepiece designed for the individual who finds beauty in astronomical precision and minimalist design.

The Craft

Powering this 9.9mm thin masterpiece is the In-house Calibre 925, an automatic movement that undergoes JLC’s rigorous "1000 Hours Control" testing. Visible through the sapphire caseback, the movement features an openworked gold oscillating weight and exquisite finishing. The contrast of the rhodium-plated "Dauphine" hands against the black dial creates exceptional legibility, while the moonphase complication adds a poetic dimension to the watch’s clinical precision.
