Master Ultra Thin Moon

The Jaeger-LeCoultre Master Ultra Thin Moon distinguishes itself with refined elegance and technical finesse, embodying the brand’s dedication to classic dress watchmaking. Introduced as part of the Master collection, this model is celebrated for its harmonious proportions and the beautifully executed moonphase complication at six o’clock—a signature touch that appeals to collectors seeking sophistication without ostentation.

The 39mm case strikes a perfect balance between contemporary presence and traditional understatement, making it versatile for both formal and everyday wear. Inside, the automatic Calibre 925 ensures reliable precision and a slim profile, contributing to the watch’s comfortable fit under a cuff. Variants differ mainly in dial color and case material, with stainless steel (reference Q1368420) being the most accessible, while pink gold versions command a premium due to their exclusivity and warm tone.

Price variations stem from material choice, dial execution, and occasionally limited editions with unique dial treatments. Lume is subtle and reserved for the hands, in keeping with the understated aesthetic. The 50m water resistance is typical for dress watches, offering peace of mind for daily use but not intended for swimming. When evaluating examples, inspect the moonphase disc for crisp printing and ensure the ultra-thin case hasn’t suffered from over-polishing, as sharp lugs and clear caseback engravings enhance both value and wrist presence.
