Blancpain Villeret Quantième Complet 8 Jours

Blancpain's Villeret Quantième Complet 8 Jours, reference 6639A 3631 MMB, comes in a 42 mm red gold case. The case measures 13.05 mm thick and the lugs take a 23 mm strap. A sapphire crystal covers the white enamel dial, which sits on the Mille Mailles strap secured by a folding clasp. Self-winding calibre 6639 drives the watch and stores a power reserve of 192 hours, unusually long for the type. The complete calendar shows date, weekday and month, with a moon phase display and small seconds completing the layout. It is a fine watchmaking piece built around a full calendar rather than a simple date window. Water resistance is rated to 30 metres.
