Blancpain Fifty Fathoms Automatique

Blancpain's Fifty Fathoms Automatique, reference 5010 1130 B64A, is a dive watch built in a 42.3 mm steel case. The case measures 14.3 mm thick, with a lug width of 21.5 mm. A sapphire crystal covers the sunburst black dial, which carries a date window and central seconds. The unidirectional rotating bezel handles timing duties in the water. Inside is the self-winding calibre 1315, with a power reserve of 120 hours, a figure well above most automatics in this category. The watch is fitted to a rubber strap with a pin buckle. Blancpain rates the case to 300 metres.
