Blancpain Fifty Fathoms Automatique

Blancpain's Fifty Fathoms Automatique, reference 5010 1130 B64B, 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 sunburst black dial sits beneath a sapphire crystal, paired with a unidirectional rotating bezel for tracking elapsed time. The self-winding calibre 1315 drives the watch, with a central seconds display and a date function, and it holds a power reserve of 120 hours. A rubber strap closes with a folding clasp. The case carries a 300 metre water resistance rating, well beyond what most divers will ever need.
