Blancpain Villeret Ultraplate Réserve de Marche 6606-3642-55B

Named after the village where Blancpain began, Villeret is the brand's classic dress collection. The watches share a slim round case with a stepped profile, enamel or opaline dials, and Roman or Arabic numerals, and they are usually made in steel or red gold.

The line is best known for its complete calendar with moon phase, a long-standing Blancpain speciality, but it also includes simple time-only models, eight-day watches, annual calendars and other complications, many of them on automatic calibers such as the 1150 and 1151 with long power reserves. Because the references differ mostly in function and dial, describe the complications precisely and confirm that every calendar indication works and is set correctly.
