Blancpain Fifty Fathoms Automatique

Blancpain's Fifty Fathoms Automatique 5007 3644A B64A is a dive watch cased in red gold at 38.2 mm across. The case measures 12 mm thick, with a lug width of 19 mm, and carries a sapphire crystal over a mother-of-pearl dial. A unidirectional rotating bezel surrounds the dial, paired with a central seconds display. The self-winding calibre 1153 drives the watch, offering a power reserve of 100 hours. It is fitted to a rubber strap with a pin buckle. The case holds a 300 metre water resistance rating, generous for a dress-proportioned dive watch of this size.
