Blancpain Bathyscaphe Quantième Complet Phases de Lune

Blancpain's Bathyscaphe Quantième Complet Phases de Lune, reference 5054 0130 NABA, is a dive watch with a 43.6 mm ceramic case. The case measures 13.4 mm thick and carries a unidirectional rotating bezel. A sapphire crystal covers the sunburst black dial, which sits above a self-winding calibre 6654.P.4 with 72 hours of power reserve. Complications include a complete calendar with date, weekday and month, along with a moon phase display and central seconds. The watch is fitted on a textile strap secured by a pin buckle. Blancpain rates the case to 300 metres, well beyond what diving requires.
