Blancpain Fifty Fathoms Automatique

Blancpain's Fifty Fathoms Automatique, reference 5015 3630 52B, comes in a 45 mm red gold case. The case measures 15.5 mm thick, with lugs spaced 23 mm apart. A sapphire crystal covers the black dial, which carries a central seconds display and a date window. The self-winding calibre 1315 drives the watch and stores 120 hours of power reserve once fully wound. Blancpain pairs the case with a sail-canvas strap secured by a folding clasp. This reference belongs to the dive watch category, built for use well beyond the desk. The folding clasp closes over a case that Blancpain rates to 300 metres.
