Overview
The Jaeger-LeCoultre Master Ultra Thin Moon 39 in blue (ref. Q1368480) pairs the manufacture's long-celebrated ultra-thin philosophy with a moonphase complication presented on a richly toned blue dial. At 39 mm in stainless steel, the case sits at a scale that honours the line's heritage of understated elegance. The moonphase and date are positioned together at 6 o'clock, lending the dial a composed, symmetrical character.
History
The Master Ultra Thin collection traces its roots to Jaeger-LeCoultre's enduring pursuit of slender, refined dress watches — a discipline the manufacture has championed for decades. The Moon 39 variant, introduced in the early 2020s, brought the moonphase complication into the 39 mm format, broadening the line's appeal to collectors who favour a more restrained case diameter. The blue-dialled reference Q1368480 entered production in 2022 and continues to represent the collection's contemporary direction. Within the broader Master Ultra Thin family, the moonphase models are consistently regarded as among the most classically complete expressions of the line.
Notable points
- Calibre 925/1 is a manufacture movement developed by Jaeger-LeCoultre specifically for the ultra-thin moonphase format.
- The 39 mm stainless steel case reflects a deliberate return to a mid-century-appropriate diameter within the Master Ultra Thin line.
- Moonphase and date are integrated at 6 o'clock, maintaining the dial's characteristic symmetry and legibility.
- The deep blue dial places the reference within a broader industry appreciation for richly coloured dress-watch dials that emerged prominently in the 2020s.
- As a Jaeger-LeCoultre manufacture piece, the movement is entirely designed, produced, and finished in-house in Le Sentier, Vallée de Joux.
