Blancpain Fifty Fathoms Automatique

Blancpain's Fifty Fathoms Automatique 5010 12B30 B52B is a dive watch with a 42.3 mm titanium case. The case measures 14.3 mm thick, with a lug width of 21.5 mm. A sapphire crystal covers the sunburst black dial, and the unidirectional rotating bezel is topped with sapphire as well. Inside is the self-winding calibre 1315, which runs for 120 hours on a full wind. The date sits on the dial alongside a central seconds hand. Blancpain fits the watch to a sail-canvas strap secured with a folding clasp. Rated to 300 metres, the case is built for genuine diving use rather than show.
