Vacheron Constantin Overseas 7900V/110A-B334

The case measures 41mm across. Case material: Steel. 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, Caliber 5110 DT. Power reserve is 60 hours. It beats at 28,800 vph.

It is rated to 150 meters, about 492 feet. That is enough for swimming and snorkeling, but not for scuba diving. 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.
