Blancpain Villeret Quantième Complet 8 Jours

Blancpain's Villeret Quantième Complet 8 Jours, reference 6639A 3631 55A, comes in a 42 mm red gold case. The case measures 13.05 mm thick, with a lug width of 23 mm. A sapphire crystal covers the cambered grand feu white enamel dial. The self-winding calibre 6639 drives the complete calendar, showing date, weekday and month alongside a moon phase display and small seconds, and stores 192 hours of power reserve. That figure is unusually long for a movement of this type. An alligator leather strap closes with a pin buckle. Water resistance is a modest 30 metres, in keeping with a dress watch of this kind.
