Blancpain Villeret Quantième Complet Demi-Savonnette

Blancpain's Villeret Quantième Complet Demi-Savonnette, reference 6664 3642 55A, has a 40 mm case in red gold. Thickness measures 11.75 mm, with a 22 mm lug width for the strap. The self-winding calibre 6654.4 runs beneath a sapphire crystal and stores 72 hours of power reserve. The stamped flinqué opaline dial shows a complete calendar with date, weekday and month, along with a moon phase display and central seconds. This combination of complications makes it a complete calendar watch in the fullest sense. An alligator leather strap closes with a pin buckle. Water resistance runs to 30 metres, modest by design given the dress-watch proportions.
