Blancpain Villeret 6651-1127-55B

The case measures 40mm across. Case material: Stainless steel (also offered in gold). Case size alone is a poor guide to how a watch wears; lug-to-lug length and how the bracelet drops off the case matter more, which is why we suggest trying one on before you commit.

Automatic, Blancpain Cal. 6654, in-house.

It is rated to 30 meters, about 98 feet. That covers rain and hand washing. It is not rated for swimming. One caution that applies to every watch on this page: a water resistance figure describes a new watch with fresh gaskets. On a piece that is years past its last service, treat the rating as unknown until it has been pressure tested.

Blancpain produced this reference from 2010 to the present day. Production years matter when you are valuing one, because dial, bezel and bracelet details often changed inside a single reference run.
