Jaeger-LeCoultre Q169242J Master Ultra Thin Tourbillon Moon Pink Gold Eggshell Dial Watch

Jaeger-LeCoultre Master Ultra Thin Tourbillon Moon – Ref. Q169242J

The Jaeger-LeCoultre Master Ultra Thin Tourbillon Moon Ref. Q169242J is a remarkable fusion of celestial complication and high horology elegance. Crafted in 18-carat pink gold with an eggshell beige dial, this 41.5 mm timepiece combines a flying tourbillon, a moon-phase display for both hemispheres, and a jumping date — all housed in a case slender for its complexity. It is designed for connoisseurs who appreciate both mechanical mastery and timeless aesthetics.

Case Dimensions

The case is made of 18-carat pink gold, measuring 41.50 mm in diameter and 12.10 mm in thickness, giving the piece strong wrist presence yet refined elegance. With 5 bar (≈ 50 meters) water resistance, it holds up to occasional exposure while emphasizing its dressy character. The case is paired with a matching pink gold double-folding buckle and interchangeable leather strap, size-adjusted (75 mm / 120 mm) for comfort. Lug width is 22 mm.

Dial Display Features

Set beneath a crystal glass, the eggshell beige dial provides a warm, soft backdrop for the intricate features. Dauphine hands and applied hour markers deliver clarity and style. At 12 o’clock, a moon-phase indicator is calibrated for both northern and southern hemispheres, allowing the wearer to track lunar cycles globally. The flying tourbillon is positioned at 6 o’clock, visible through an open aperture that also accommodates a date display that “jumps” from the 15th to the 16th — a design solution to preserve the tourbillon’s symmetry and function.

Movement Technical Excellence

This model is powered by Jaeger-LeCoultre Calibre 983 (983AA), a self-winding movement combining tourbillon, moon phase, date, hours, minutes, and seconds. It beats at 28,800 vph (4 Hz), contains 35 jewels, and offers a 45-hour power reserve. The movement’s height is engineered to support the complexity while maintaining the watch’s overall slim profile.

Strap, Buckle Wearability

Equipped with a high-quality alligator leather strap in classic black, the Q169242J features an interchangeable design. A pink gold double-folding buckle ensures both security and style. The standard lengths (75 mm / 120 mm) and the 22 mm lug width support a comfortable fit across a broad range of wrist sizes. Despite its complexity, the case shape and strap design help it sit harmoniously beneath shirt cuffs for dress occasions.
