Bathyscaphe Quantième Complet Phases de Lune
Ref. 5054 01
The Blancpain Bathyscaphe Quantième Complet Phases de Lune is a highly complicated dive watch featuring a complete calendar, moon phase display, and a 300-meter water resistance. It is notable for its black ceramic case, a first for the Bathyscaphe collection, and its intricate complications, making it a standout piece in Blancpain’s heritage line. Introduced in 2024, it combines technical precision with a refined aesthetic, including hand-finished bracelet links for a bespoke fit.
