Aqua One Watch for casual wear

The Oceanaut Aqua One OC2810 is a casual wristwatch built for adult men who want a straightforward timepiece with a black stainless steel case and black dial. Its quartz movement keeps time without winding, and the round 40 mm case fits a classic silhouette.

20 ATM water resistance for swimming

Water resistance rated at 20 ATM, 200 metres or 660 feet lets the watch handle swimming and surface water sports without needing extra seals or a screw-down crown. The mineral crystal resists everyday scratches so the dial stays legible after pool or ocean use.

Silicone strap with 18 mm lug width

The black silicone band fastens with a stainless steel buckle and adjusts to a 7 inch length, while the 18 mm lug width accepts standard aftermarket straps if the owner wants a different look. No proprietary tools are required for a quick swap.

Questions about this item

How long will the quartz movement run before the battery needs changing?

A typical quartz cell lasts two to three years with normal wear; the watch itself has no rechargeable limit.

Does the 20 ATM rating mean the case or crown gets hot during long dives?

Water resistance is a static pressure rating; the stainless steel case and mineral crystal do not generate heat, so temperature stays ambient.

Will the 18 mm silicone strap fit my existing spring bars?

The lug width is 18 mm, so any standard 18 mm spring bars will work with the supplied strap.
