Jaeger-LeCoultre Master Ultra Thin Moon – Ref. Q1362511
The Jaeger-LeCoultre Master Ultra Thin Moon Ref. Q1362511 is a superb example of refined horology where elegance meets utility. With a 39 mm case in 18-carat rose gold, an eggshell beige dial, a moon-phase indication, and an ultra-thin profile, this timepiece strikes the perfect balance for someone who appreciates both classic charm and modern craftsmanship.
Case & Build Quality
The case is crafted in 18-carat pink (rose) gold, with a diameter of 39 mm and a case thickness of approximately 9.3 mm, giving the watch a graceful and dress-friendly footprint. The water resistance is rated at 5 bar (~50 meters), so it handles everyday exposure such as rain or splash without compromising its refined appearance. The sapphire crystal over the dial and a sapphire caseback protect both dial and movement.
Dial, Hands & Moon-Phase Display
Beneath the crystal lies an elegant eggshell beige dial that exudes warmth and understated luxury. Rose gold dauphine hands and applied gilt (rose gold) hour markers give clean, classic readability. At 6 o’clock is a combined date and moon-phase display that adds poetic charm, allowing the owner to follow lunar cycles with grace. A central seconds hand sweeps with precision, complementing the primary time display.
Movement & Technical Specifications
Powering the Q1362511 is Jaeger-LeCoultre’s in-house Calibre 925, an automatic movement. It operates at 28,800 vibrations per hour (4 Hz), contains 30 jewels, and consists of 245 components. Outstanding in this reference is the 70-hour power reserve, meaning the watch can run for nearly three days off the wrist without winding. The movement thickness is about 4.9 mm, which helps the overall thinness of the watch.
Strap, Clasp & Wearability
The Q1362511 comes with a black alligator leather strap, which complements the warm tones of the rose gold case and the beige dial. The strap is interchangeable, allowing customization. Strap dimensions are about 75 mm on the 12 o’clock side and 120 mm on the 6 o’clock side; lug width is 21 mm. The buckle is a pink gold pin buckle matching the case material. This combination ensures comfort and elegance for both daily wear and special occasions.
