Inspired by modern style and streamlined design, theMaster Ultra Thin Collection features timeless aesthetics, clean lines, and exceptional watchmaking. Inheriting the design of its case from the first ultra-thin pocket watch of 1907, each piece boasts understated elegance and is powered by sophisticated movement. Sleek and simple, the 39mm ultra thin stainless steel case is presented on an understated interchangeable black leather strap, secured by a double folding buckle. Powered by Jaeger-LeCoultre 899 caliber automatic movement, this watch is equipped with a 38-hour power reserve and water resistance to 5 bar (50 meters) offering high-performance at every hour. The silvered-gray dial houses Dauphine hands alongside a date display at 6 o’clock.
