Citizen Promaster Diver BN0150-28E

The case measures 44mm across and 12mm thick, with a 20mm lug width. Case material: Stainless 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.

Eco-Drive quartz, Citizen Cal. E168 (light-powered).

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.

Citizen produced this reference from 2016 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.
