Jaeger-LeCoultre Q1242502 Master Ultra Thin Moon Pink Gold – Diamond Silver Dial Watch

Jaeger-LeCoultre Master Ultra Thin Moon 36 mm – Ref. Q1242502

The Jaeger-LeCoultre Master Ultra Thin Moon Ref. Q1242502 is a refined dress watch that embodies timeless elegance and subtle sophistication. Featuring an 18-carat pink gold case, a moon-phase complication, and a diamong-set bezel, this 36 mm timepiece balances graceful proportions with technical merit. It is designed for those who appreciate heritage craftsmanship and polished style rolled into one.

Case & Overall Dimensions

The watch is housed in a warm 18-carat pink gold case measuring 36.00 mm in diameter and approximately 9.40 mm in thickness. Water resistance is rated at 5 bar (≈50 meters), sufficient for everyday wear though not a dive specification. The bezel is beautifully set with brilliant-cut diamonds, adding sparkle without overshadowing the minimalist elegance of the design.

Silvered-Grey Sunray Dial & Hands

Beneath a sapphire crystal lies a silvered-grey dial with a sunray brushed finish. Dauphine hands impart classic grace, and gilt hour markers offer refined contrast and readability. The dial artfully integrates a moon-phase display, maintaining balance and symmetry. The small seconds are subtly placed to preserve clarity while enhancing utility.

Movement & Power Reserve

Powering the Q1242502 is the Jaeger-LeCoultre in-house automatic calibre 925AA. This movement offers 70 hours of power reserve, operating at 28,800 vph (4 Hz), with 30 jewels. Its slim sector movement has a thickness around 4.9 mm, which helps the overall case stay elegant while including complications like the moon phase and date. The exhibition case-back reveals the movement’s finishing and rotor, a delight for horology lovers.

Dial Layout & Complications

In addition to the standard hour, minute, and second hands, the watch includes a moon-phase complication positioned in the lower half of the dial, with the date integrated in a sub-dial or aperture. The moon phase is clearly rendered and adds a poetic dimension to this ultra-thin dress piece. Every element is arranged for legibility and elegance.

Strap, Buckle & Wearability

This reference comes on a black alligator leather strap, providing classic dress-watch character. Lug width is 17 mm, adding to its graceful wrist presence. The strap is fitted with a pink gold pin buckle. The combination of the leather strap, slim case, and the warm rose-gold finish makes this watch versatile for both formal wear and elegant daily use.
