Blancpain Villeret Quantième Perpétuel Phases de Lune

Blancpain's Villeret Quantième Perpétuel Phases de Lune, reference 6656 3642 55B, has a 40.3 mm case in red gold. The case measures 10.7 mm thick, with a lug width of 22 mm suited to the alligator leather strap. A sapphire crystal covers the opaline dial, which runs on the self-winding calibre 5954.4 with 72 hours of power reserve. The perpetual calendar tracks the date without correction across leap years, and a moon phase display sits alongside a central seconds hand. The strap closes with a folding clasp in the same red gold as the case. Water resistance is a modest 30 metres, enough for daily wear away from water.
