Blancpain Fifty Fathoms Automatique

Blancpain's Fifty Fathoms Automatique 5010 12B40 O64B is a dive watch with a 42.3 mm titanium case. The case stands 14.3 mm thick, with a lug width of 21.5 mm. A unidirectional rotating bezel surrounds the sunburst blue dial, which sits under a sapphire crystal and shows the date along with central seconds. The self-winding calibre 1315 drives the watch and stores 120 hours of power reserve, a substantial figure for an automatic movement. Blancpain fits the piece on a rubber strap with a folding clasp. Rated to 300 metres, the case is built for actual diving rather than just the look of it.
