Blancpain Fifty Fathoms 5015-3630-52A

This reference designates the Fifty Fathoms Automatique in 18k rose gold, specifically on a sail-canvas strap. Its significance lies in taking the legendary tool watch and elevating it to a piece of high luxury. It retains the iconic 45mm case, black dial, and sapphire bezel, but the satin-brushed rose gold construction provides a warm, precious metal aesthetic. It is powered by the high-performance Caliber 1315 with a 120-hour power reserve. The “-52A” suffix distinguishes this version by its pairing with a durable and sporty sail-canvas strap, offering a more understated option than a full gold bracelet.
