Blancpain Bathyscaphe Quantième Complet Phases de Lune

Blancpain's Bathyscaphe Quantième Complet Phases de Lune, reference 5054 1110 B52A, is a steel case measuring 43 mm across. The case stands 13.4 mm thick, with lugs set at 23 mm apart. A sapphire crystal covers the sunburst grey dial, which sits above the self-winding calibre 6654.P.4 and its 72-hour power reserve. This complete calendar shows date, weekday and month alongside a moon phase display and central seconds. The watch pairs diving capability with a full complication set, a combination not often seen in the same case. It comes on a sail-canvas strap secured with a pin buckle. The screw-down build holds water resistance to 300 metres.
