Master Ultra Thin Moon 36mm in Pink Gold: Jaeger-LeCoultre Q1242521

Jaeger-LeCoultre Master Ultra Thin Moon Q1242521 in 36mm pink gold, priced at AED 89,000 in the UAE. Calibre 925, moon phase, 70h power reserve.

Editorial Take

• At AED 89,000 in the UAE (CHF 19,800 in Switzerland), the Jaeger-LeCoultre Master Ultra Thin Moon Q1242521 places an 18-carat pink gold case, the Calibre 925 automatic movement, and a moon phase complication within reach of collectors who have long admired the line from a distance.
• The 36mm diameter and 9.34mm case thickness keep the proportions firmly within dress-watch territory.
• The Calibre 925 runs at 4 Hz with a 70-hour power reserve and 245 components across 30 jewels.
• A stainless steel variant (Q1248421) is offered at AED 37,400 with the same movement and proportions.

Design and Proportions

At 36mm across and 9.34mm deep, the polished pink gold case sits low on the wrist without competing for visual space. The thin bezel and elongated lugs are carried over from the larger references in the Master Ultra Thin family, so the proportions feel considered rather than simply scaled down.

The silvered grey sunray-brushed dial carries gilt hour-markers alongside Dauphine and baguette hands. Up close, the midnight blue moon phase aperture anchors the lower half of the dial: the moon and stars are rendered in polished rose gold, their relief catching light differently from the brushed grey ground behind them.

Movement and Technical Detail

The Calibre 925 is an in-house automatic beating at 28,800 vibrations per hour (4 Hz). Its 4.9mm thickness is well-suited to the 9.34mm overall case depth. The 70-hour power reserve comes from a single barrel across 245 components and 30 jewels, and the functions extend to hours, minutes, seconds, a pointer date, and the moon phase itself.

The black alligator strap with large scales uses a quick-release interchangeable system at a lug width of 17mm, secured by a pink gold 750/1000 pin buckle.

Within the Collection

The same 36mm case and Calibre 925 movement are offered in stainless steel as reference Q1248421, with a sunrayed silver dial rather than the sunray-brushed grey of the pink gold version. At AED 37,400 against AED 89,000, the steel variant addresses a different price bracket while keeping the technical specification identical. For collectors weighing the two, the choice is primarily one of metal and dial character, not complication or movement.
