Blancpain Villeret Grande Date Jour Rétrograde

Blancpain's Villeret Grande Date Jour Rétrograde, reference 6668 3642 55A, comes in a 40.5 mm red gold case. The case measures 11 mm thick, with a lug width of 22 mm. A sapphire crystal covers the opaline dial, which carries a central seconds display alongside a large date and a retrograde weekday indication. Inside is the self-winding calibre 6950GJ.4, giving 72 hours of power reserve. The dial's clean layout leaves room for these two complications without crowding the hour markers. An alligator leather strap closes with a pin buckle. Water resistance is a modest 30 metres, enough for daily wear but not for swimming.
