Blancpain Fifty Fathoms Automatique

Blancpain's Fifty Fathoms Automatique 5007 36B40 O52B is a dive watch cased in red gold at 38.2 mm across. The case stands 12 mm thick, with lugs spaced 19 mm apart, and carries a sapphire crystal over a sunburst blue dial. A unidirectional rotating bezel sits above it, paired with a date display and central seconds. The self-winding calibre 1150 drives the watch and stores 100 hours of power reserve, a notable figure for the collection. Blancpain fits the piece to a sail-canvas textile strap closed with a folding clasp. The case holds a 300 metre water resistance rating, generous for a dress-leaning dive watch of this size.
