Blancpain Fifty Fathoms Automatique

Blancpain's Fifty Fathoms Automatique 5007 3644A B64B is a dive watch with a 38.2 mm case in red gold. The case measures 12 mm thick, with a lug width of 19 mm. A unidirectional rotating bezel surrounds the sapphire crystal, which sits over a mother-of-pearl dial with subtly graduated black colouring. Inside is the self-winding calibre 1153, running with a power reserve of 100 hours. The central seconds function keeps time easy to read at a glance. Blancpain pairs the case with a rubber strap on a folding clasp. Water resistance reaches 300 metres, well beyond what diving requires.
