Blancpain Villeret Quantième Perpétuel Phases de Lune

Blancpain's Villeret Quantième Perpétuel Phases de Lune, reference 6656 3642 55A, has a 40.3 mm case in red gold. The case measures 10.7 mm thick, with lugs set 22 mm apart, and the opaline dial sits under a sapphire crystal. Inside is the self-winding calibre 5954.4, with a power reserve of 72 hours. The watch combines a perpetual calendar with a moon phase display, along with a date and central seconds. These functions are laid out on the dial without crowding it, in keeping with Villeret's plain, symmetrical style. An alligator leather strap closes with a pin buckle. Blancpain rates the case to 30 metres.
