Jaeger-LeCoultre Master Ultra Thin Moon 39mm 176.8.64.S Black Dial

The Jaeger-LeCoultre Master Ultra Thin Moon, reference 176.8.64.S, is a refined and elegant dress watch that showcases the brand’s mastery of ultra-thin horology and complications. Its 39 mm case — typically crafted in stainless steel or precious metal — houses a sleek black dial with a subtle sunburst finish, featuring applied hour markers, dauphine hands, and a sophisticated moon phase display at 6 o’clock — a signature complication that adds poetic charm to its minimalist design.

Powered by Jaeger-LeCoultre’s in-house Caliber 846 — an ultra-thin automatic movement with a 45-hour power reserve — the watch delivers precision and reliability in a remarkably slim profile. The black dial is often paired with a matching alligator strap or a polished steel bracelet, ensuring a refined, comfortable fit for formal or everyday wear. With 50 meters of water resistance, it’s built for elegance, not active use. As a modern expression of JLC’s heritage, the Master Ultra Thin Moon 176.8.64.S is a timeless choice for those who value understated luxury, mechanical artistry, and the quiet beauty of complications.
