Blancpain Bathyscaphe Quantième Complet Phases de Lune

Blancpain's Bathyscaphe Quantième Complet Phases de Lune, reference 5054 1110 NABA, has a 43 mm steel case. It measures 13.4 mm thick, with a lug width of 23 mm. A sapphire crystal covers the sunburst grey dial. The self-winding calibre 6654.P.4 drives the watch, with 72 hours of power reserve and a full calendar showing date, weekday and month alongside a moon phase display and central seconds. It rides on a textile strap fitted with a pin buckle. Blancpain rates the case to 300 metres, solid figures for a watch that pairs diving credentials with a complete calendar.
