Blancpain Fifty Fathoms Automatique

Blancpain's Fifty Fathoms Automatique, reference 5015 1130 52A, is a dive watch with a 45 mm steel case. The case measures 15.5 mm thick, and the lugs take a 23 mm strap. A unidirectional rotating bezel surrounds the black dial, which sits under a sapphire crystal and shows the date alongside a central seconds hand. The self-winding calibre 1315 drives the watch and stores 120 hours of power reserve. Blancpain fits the case to a sail-canvas strap with a pin buckle. Rated to 300 metres, the case suits the watch's underwater intent.
