Blancpain Villeret Quantième Complet 8 Jours

Blancpain's Villeret Quantième Complet 8 Jours, reference 6639 3642 55B, is a red gold watch with a case diameter of 42 mm. The case measures 13.05 mm thick and takes a lug width of 23 mm. A self-winding movement, calibre 6639, drives the watch and stores 192 hours of power reserve, enough to let it run over a full week without winding. The opaline dial sits under a sapphire crystal and displays a complete calendar with date, weekday and month, alongside a moon phase and small seconds. An alligator leather strap closes with a folding clasp. Water resistance is modest: Blancpain rates the case to 30 metres.
