Rolex Sea-Dweller Deepsea 126660

The case measures 44mm across and 17.7mm thick, with a 22mm lug width. Case material: 904L Oystersteel, Ringlock System. 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, Rolex Cal. 3235. Power reserve is 70 hours. It beats at 28,800 vph. The movement uses 31 jewels.

It is rated to 3900 meters, about 12795 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.

Rolex produced this reference from 2014 to the present day. Production years matter when you are valuing one, because dial, bezel and bracelet details often changed inside a single reference run.
