Blancpain Fifty Fathoms Automatique

Blancpain's Fifty Fathoms Automatique 5010 1130 NABA 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 sapphire crystal covers the sunburst black dial, which carries a date window and central seconds. The self-winding calibre 1315 drives the watch and stores 120 hours of power reserve, a notably long figure for the category. A unidirectional rotating bezel sits at the case edge, matching the tool-watch layout expected of the line. The watch comes on a NATO-style textile strap fitted with a pin buckle. Blancpain rates the case to 300 metres.
