Blancpain Villeret Ultraplate

Blancpain's Villeret Ultraplate, reference 6605 3642 55B, has a 39.7 mm case in red gold. The case measures 7.45 mm thick, with lugs set at 22 mm. Manual-winding calibre 11A4B drives the watch, and the opaline dial sits under a sapphire crystal. Central seconds are joined by a power reserve display, and the movement runs for 100 hours on a full wind, which is unusually long for a hand-wound calibre. An alligator leather strap closes with a folding clasp. Blancpain rates the case to 30 metres, enough for splashes but not for swimming.
