Casual 38 mm quartz watch

The Oceanaut OC0811 is a round quartz watch with a 38 mm stainless steel case and a black dial. A silicone strap 18 mm wide fastens with an adjustable clasp. Mineral crystal protects the face, and a date window sits at three o'clock. Water resistance is rated to 3 ATM, equal to 30 metres or 100 feet.

Suits daily wear; not for timing or diving

This model fits adults who want a simple casual watch for everyday use. The quartz movement keeps time without winding. Buyers who need a chronograph function for stopwatch timing should look elsewhere. The 3 ATM rating covers splashes and brief immersion but not swimming or diving.

38 mm case diameter

The case measures 38 mm across, a compact size that sits flush on smaller wrists. Combined with the 18 mm strap width it determines how the watch wears and whether it matches existing bands. Check this dimension against your wrist and any strap you plan to reuse.

Questions about this item

How do I fit the 18 mm silicone strap and what step is often missed?

The strap uses standard 18 mm spring bars; the step most people skip is checking that both bars click fully into the lug holes before wearing the watch.

What part will need replacement first on the OC0811?

The quartz movement runs on a button cell; expect to change the battery every couple of years when the seconds hand starts jumping in four‑second steps.

What limit appears first if I keep the watch wet for long periods?

Water resistance is rated to 30 metres or 100 feet; prolonged immersion beyond splashes or brief swimming can let moisture past the seals.
