Common questions about the Tudor Submariner 7021

How big is the Tudor Submariner 7021?

The case measures 40mm across, with a 20mm lug width. 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.

What movement is in the 7021?

Automatic, ETA 2484. The movement uses 25 jewels.

Is the 7021 water resistant?

It is rated to 200 meters, about 656 feet. That is a diving rating: it is built for scuba use, not just for getting wet. 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.

When was the Tudor Submariner 7021 made?

Tudor produced this reference from 1969 to 1970. Production years matter when you are valuing one, because dial, bezel and bracelet details often changed inside a single reference run.

Does the 7021 have a nickname?

Submariner Date. Collector nicknames are not official Tudor names, but they are what people actually search for and what they are called across a showroom.
