Blancpain Fifty Fathoms Automatique

Blancpain's Fifty Fathoms Automatique 5010 1130 B52A is a dive watch with a 42.3 mm steel case. The case measures 14.3 mm thick, with a lug width of 21.5 mm. A sapphire crystal covers the sunburst black dial, which carries a central seconds hand and a date window. A unidirectional rotating bezel surrounds the dial, allowing elapsed dive time to be tracked. The self-winding calibre 1315 drives the watch and stores 120 hours of power reserve. A sail-canvas strap closes with a pin buckle. Blancpain rates the case to 300 metres, in keeping with the model's dive-watch purpose.
