Blancpain Villeret 8 Jours

Blancpain's Villeret 8 Jours, reference 6630 1531 55B, comes in a 42 mm white gold case. The case measures 11.25 mm thick, with a lug width of 23 mm. A sapphire crystal covers the white grand feu enamel dial. Inside is the self-winding calibre 1335, notable for its 192 hour power reserve, a rare figure that gives the "8 Jours" (eight days) name its meaning. The date sits alongside a central seconds display. The watch is fitted to an alligator leather strap with a folding clasp. Water resistance is modest here: Blancpain rates the case to 30 metres, adequate for a dress watch of this kind.
