Blancpain Villeret Quantième Perpétuel Phases de Lune

Blancpain's Villeret Quantième Perpétuel Phases de Lune, reference 6656 3642 MMB, has a 40.3 mm case in red gold. The case measures 10.7 mm thick and the lug width comes in at 22 mm. A sapphire crystal covers the opaline dial, and the case is fitted with a self-winding calibre 5954.4 that runs with 72 hours of power reserve. The watch combines a perpetual calendar with a moon phase display, alongside date and central seconds functions. This pairing places the model firmly among Blancpain's most complicated Villeret pieces. A Mille Mailles strap closes with a folding clasp. The case holds a water resistance rating of 30 metres.
