Blancpain Fifty Fathoms Automatique

Blancpain's Fifty Fathoms Automatique, reference 5015 12B40 98B, is a dive watch with a 45 mm titanium case. The case measures 15.4 mm thick, and the lug width comes in at 23 mm. A sapphire crystal covers the sunburst blue dial, which shows the date and a central seconds hand. The self-winding calibre 1315 drives the watch and stores 120 hours of power reserve. A unidirectional rotating bezel surrounds the dial, matching the tool-watch character of the case. The titanium bracelet closes with a folding clasp. Blancpain rates the case to 300 metres, well beyond what casual diving requires.
