Blancpain Fifty Fathoms Automatique

Blancpain's Fifty Fathoms Automatique 5010 36B30 B52B is a dive watch with a red gold case measuring 42.3 mm across. The case stands 14.3 mm thick and carries a unidirectional rotating bezel, a signature of the collection. Inside is the self-winding calibre 1315, with 120 hours of power reserve, visible through a sapphire crystal. The black sunburst dial shows a date window and a central seconds hand. Blancpain fits the watch on a textile strap with a folding clasp, keeping it practical for daily wear despite the precious metal case. Rated to 300 metres, the case meets the depth requirements of serious diving.
