Common questions about the Zenith Defy 03.9300.3620/01.I001

How big is the Zenith Defy 03.9300.3620/01.I001?

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.

What movement is in the 03.9300.3620/01.I001?

Caliber 3620. Power reserve is 60 hours. It beats at 36,000 vph.

Is the 03.9300.3620/01.I001 water resistant?

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.

Does the 03.9300.3620/01.I001 have a nickname?

Defy Skyline. Collector nicknames are not official Zenith names, but they are what people actually search for and what they are called across a showroom.
