Identified by reference 1362511, the Jaeger-LeCoultre Master Ultra Thin Moon 39 is the rose gold moon phase of the line rather than a time-only dress watch. This JLC Master Ultra Thin replica still keeps the philosophy the collection is built on: a round case held to the thinnest possible profile. At 39mm the case diameter sits in the contemporary sweet spot for dress watches, large enough to read comfortably but restrained enough to disappear under a cuff. The Ultra-Thin Master line occupies a distinct position within the broader Master collection, where slimness is the primary engineering constraint rather than an afterthought. Every design decision in this reference, from the movement architecture to the crystal profile, serves the goal of minimizing case height.

The 1362511 runs a blued central seconds hand over a silvered eggshell dial, with gold applied baton indices and AUTOMATIQUE printed on the dial. The moon phase display is ringed by its date scale, which gives this Master Ultra Thin super clone two indications beyond the time while the dial surface stays uncluttered.

What Collectors Notice

Ultra-thin watches reveal their quality through how they sit on the wrist rather than how they look on a dial photograph. The 1362511 should feel like a heavy coin rather than a bulky instrument, with the weight distributed evenly across the caseback surface. Jaeger-LeCoultre has produced ultra-thin calibers since the 1907 Calibre 145, and the engineering lineage is visible in how confidently this 39mm case maintains its slim proportions without feeling fragile. The 1368480 reference offers a different dial treatment within the same Ultra-Thin Master family. Both belong to the full Ultra-Thin Master collection, which ranges from time-only models to moon phase and perpetual calendar complications built on the same slim foundations.

This vs Other Versions

Within the Ultra-Thin Master range, the 1362511 sits between the time-only references and the perpetual calendars. It carries a moon phase with a date ring around it, two indications added to the dial without the extra height a full calendar layout demands. Reserve de marche references trade that moon phase for a power reserve indicator, and the other Moon 39 cases in the range are steel, which makes this JLC Master Ultra Thin replica the rose gold option within the same dial layout. Fitting that complication into a 9.9mm case is exactly what the Ultra-Thin Master concept was designed to achieve.

Rose gold makes this the outlier among the Moon 39 dials, and where the Moon 39 sits alongside the Date and the perpetual calendar is laid out on a single page. For the brand-wide view, how the Moon 39 ranks among JLC super clones is the shorter read.
