Blancpain Fifty Fathoms Automatique

Blancpain's Fifty Fathoms Automatique 5015 12B40 O52B is a dive watch with a titanium case measuring 45 mm across. The case stands 15.4 mm thick, with a lug width of 23 mm. A sapphire crystal covers the sunburst blue dial, which carries a date window and a central seconds hand. Inside is the self-winding calibre 1315, with a power reserve of 120 hours. The unidirectional rotating bezel is finished to match the case and allows dive time to be tracked at a glance. Blancpain fits the watch to a sail-canvas strap on a folding clasp. Water resistance reaches 300 metres, well suited to the watch's purpose.
