Sports watch for everyday timing

The Casio AMW-870A-2AV combines analog hands with a digital readout in a stainless steel case. A resin strap and buckle clasp keep it secure during activity. Quartz movement drives the timekeeping, while mineral crystal protects the blue dial. Water resistance to 50m suits daily wear and light swimming.

Replaces single-display watches

Moving from a purely analog or purely digital piece adds world time, month, day and date without extra buttons. The jump is worth it when you want at-a-glance dual-zone reading and calendar data on one wrist. Index markers at 12, 3 and 9 keep the analog face readable in low light.

Simple strap-on fitting

The resin band threads through the fixed lugs and locks with the buckle clasp in seconds. No tools are required for sizing. What usually goes wrong is overtightening the clasp, which stresses the resin, or forgetting to screw the crown down before water exposure, risking moisture ingress.

Questions about this item

Will the 44.00 mm stainless-steel case clear a standard 12 mm buckle clasp without interference?

Yes, the 44.00 mm case and supplied resin strap are designed for the 12 mm buckle clasp, so no modification is needed.

What is the correct sequence to set the analog hands after the digital world-time module is configured?

Pull the crown to the second click, rotate until the hands match the digital time, then push the crown fully in to restart the quartz movement.

How often should the mineral crystal gasket be inspected to maintain the 50 m water resistance?

Have the gasket checked at every battery change, roughly every two to three years, and replace it if any wear is visible.
