Master Ultra Thin Reserve De Marche

Inspired by modern style and streamlined design, the Master UltraThin 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. The sleek 39mm stainless steel case is presented on a timeless black alligator leather strap and secured by a double folding buckle. The luxurious silvered sunray-brushed dial in accentuated by elongated rhodium-plated hour markers and hour and minute hands, alongside power reserve, seconds and date complications. The powerful Jaeger-LeCoultre 938 caliber automatic winding movement lies at the heart of this robust timepiece, boasting a 43-hour power reserve and water resistance of 5 bar (50 meters).
