Solar-powered sports watch

The Casio AQS810W-1AV combines analog hands with a digital LCD for men who want a single timepiece for daily wear and sport. Tough Solar charging keeps the rechargeable cell topped up without cable charging. A 52 mm resin case and matching strap sit at 1.41 oz on the wrist.

Power reserve and water resistance

Solar charging feeds a power-save mode and battery indicator so the movement stays running in low light. Water resistance is rated to 328.08 ft for swimming and surface water sports. Quartz movement maintains steady timing between light exposure.

Resin build and strap adjustment

Black resin case and band resist sweat, salt and impact during training sessions. Buckle fastener allows quick on-off and fine length adjustment for different wrist sizes. Dual time, 48-city world time, 5 alarms, 1/100-second stopwatch and dual countdown timers cover travel and interval workouts.

Questions about this item

How do I install the resin band and set the 48-city world time, and what step do people often miss?

Fasten the buckle on the 52 mm case, then hold the adjust button to enter world-time mode and scroll to your city code; the step many miss is confirming the 12/24-hour format before saving.

What maintenance will the Tough Solar power system need after a few years?

The rechargeable cell is charged by light; keep the dial exposed to bright light regularly and avoid long dark storage, and the cell typically lasts several years before needing professional replacement.

Which limit appears first during continuous stopwatch use — battery drain or water resistance?

Water resistance is rated to 328.08 ft and is unaffected by stopwatch operation; the 1/100-second stopwatch draws minimal power from the solar cell, so battery drain is not the limiting factor.
