Tudor Chronograph 79280

The case measures 40mm 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 chronograph, ETA/Valjoux 7750. Power reserve is 44 hours. It beats at 28,800 vph. The movement uses 25 jewels.

It is rated to 100 meters, about 328 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.

Tudor produced this reference from 1995 to 2000. Production years matter when you are valuing one, because dial, bezel and bracelet details often changed inside a single reference run.
