Jaeger-LeCoultre Master Ultra Thin Moon 39 Q1368420

Pure lines and an aesthetically refined dial. A graceful ballet brings the dial to life with the moon-phase display. Sapphire crystal case back reveals the movement. Only 4.9 mm thick, this ultra-thin movement is proof that technique and sophistication, however extreme, can happily coexist inside a narrow space.

Automatic movement, 30 jewels, silvered dial with gilt hour-markers, and power reserve of 43 hours.
