Blancpain Fifty Fathoms Automatique

Blancpain's Fifty Fathoms Automatique 5015 1130 52B is a dive watch with a 45 mm steel case. The case measures 15.5 mm thick, a substantial figure that suits the tool-watch proportions of the collection. The black dial sits under a sapphire crystal and carries date and central seconds displays. A unidirectional rotating bezel surrounds the dial for tracking elapsed dive time. Inside is the self-winding calibre 1315, which stores a 120 hour power reserve, so the watch can sit unworn over a weekend and still run on Monday. The watch is fitted to a sail-canvas strap, with a lug width of 23 mm. The folding clasp secures the case to its 300 metre rating.
