48 mm stainless steel diver

The Oceanaut OC2911 is a 48 mm stainless steel watch with a quartz movement and a matching metal bracelet. It offers 20 ATM water resistance rated to 200 metres or 660 feet and a scratch-resistant mineral crystal. A black dial with a date window completes the casual design. The fold-over clasp secures the 24 mm wide band on the wrist.

Suits daily wear and swimming

This watch fits adults who want a single timepiece for office, weekend and pool use. The 48 mm case diameter may feel large on slender wrists, so buyers preferring a more compact profile should look elsewhere. No chronograph function is included, so users needing stopwatch timing will need a different model.

20 ATM water resistance decides

The 20 ATM rating is the specification that determines whether this watch matches the buyer's depth requirements. It covers recreational diving and high-impact water sports up to 200 metres. If the intended use stays at surface level only, a lower-rated model would also suffice.

Questions about this item

What case diameter and lug width does the OC2911 have for strap compatibility?

The case measures 48 mm across and the bracelet is 24 mm wide at the lugs, so any replacement strap must match that 24 mm lug width.

How is the fold-over clasp adjusted on the stainless steel bracelet, and what step is often missed?

Open the clasp, slide the micro-adjust holes to the desired position, then snap the clasp shut; the step often missed is ensuring the safety latch clicks fully closed.

When will the quartz movement need a battery change, and what seal work is required at that time?

Expect a battery change every few years; at each swap the case back gasket should be inspected and replaced if worn to keep the 20 ATM / 200 m / 660 ft rating intact.
