Common questions about the Rolex Explorer II 226570 Black

How big is the Rolex Explorer II 226570 Black?

The case measures 42mm across, with a 21mm lug width. Case material: Oystersteel. 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 226570 Black?

Automatic, Rolex Cal. 3285. Power reserve is 70 hours. It beats at 28,800 vph. The movement uses 31 jewels.

Is the 226570 Black 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.
