Master Ultra Thin Moon 39 Blue Dial | Ref. Q1368480 | 2026 Brand New Full Set

The Story

The Jaeger-LeCoultre Master Ultra Thin Moon 39 (Ref. Q1368480) is widely considered by horological purists to be the quintessential modern dress watch. Jaeger-LeCoultre, historic provider of movements to the world's most elite watch maisons, pours its legendary technical mastery into the Master Ultra Thin family. This specific reference reimagines classical dress elegance by replacing traditional silver faces with a deeply rich, captivating petrol blue sunburst dial. It is a timepiece designed for the discerning individual who values understated luxury, horological pedigree, and an artistic layout that sits with perfect sophistication on the wrist.

The Craft: Ultra-Thin Architecture & Astronomical Poetry

The stainless steel case is a marvel of ergonomic engineering, measuring a perfectly balanced 39mm in diameter with a razor-thin profile of just 9.3mm. This allows the watch to slide completely unnoticed beneath the crispest bespoke shirt cuff, while still maintaining an elite presence.

The sunburst dial is a dynamic canvas, shifting character from a vibrant royal azure in direct sunlight to a moody midnight black in dim settings. It hosts applied faceted white gold hour markers and classic dauphine hands. At 6 o'clock sits the centerpiece complication: a gorgeously integrated moonphase display surrounded by a circular pointer date scale, track the lunar cycle against a star-studded golden sky.

Beating inside is the immaculate In-house Jaeger-LeCoultre Calibre 925. This ultra-thin automatic winding movement is built, decorated, and tested to the rigorous "1000 Hours Control" standard of the Maison. It features a skeletonized 21K gold oscillating weight and delivers supreme long-term reliability.
