Blancpain Bathyscaphe Quantième Complet Phases de Lune

Blancpain's Bathyscaphe Quantième Complet Phases de Lune, reference 5054 0130 01S, is a dive watch built entirely from ceramic and measuring 43.6 mm across. The case stands 13.4 mm thick and carries a unidirectional rotating bezel finished in the same material. A sapphire crystal covers the sunburst black dial, which sets the moon phase display alongside a complete calendar showing date, weekday and month. Central seconds round out the display. Self-winding calibre 6654.P.4 drives the watch, holding a 72-hour power reserve. The ceramic bracelet closes with a folding clasp, and lug width comes to 23 mm. Rated to 300 metres, the case retains full diving credentials despite its complications.
