Sports Watch for Active Use

The Casio G-Shock GA-100WD-1A is a quartz watch built with a resin case and strap for daily wear. Its analog and digital display shows the time, month, day and date at a glance. Water resistance is rated to 200 metres, making it suitable for swimming and surface water sports. Shock-resistant construction protects the module from knocks and vibration.

Upgrade from Basic Digital Models

This model replaces simpler digital-only watches by adding analog hands alongside the LCD readout. The white dial with index markers improves legibility in bright conditions compared with darker faces. Buyers who want more storage or a second time-zone function will not find those features here. The fixed bezel and buckle clasp keep the design straightforward for everyday use.

Resin Build Fits Casual and Wet Environments

The 51.20 mm resin case sits on a matching resin band secured by a buckle clasp, so no metal parts contact the skin. Mineral crystal covers the dial, resisting scratches better than acrylic. Quartz movement runs on a standard battery, removing the need for winding or motion to keep time. The 200 metre rating frees the wearer from removing the watch for pool sessions or rain.

Questions about this item

What wrist size does the 51.20 mm thick resin case and resin strap fit?

The 51.20 mm case thickness and adjustable resin strap with buckle clasp accommodate most adult male wrists; the strap can be trimmed or punched for a precise fit.

How do I set the analog and digital displays, and which step is often missed?

Pull the crown to adjust the analog hands, then use the mode and adjust buttons to sync the digital month, day and date display; the step often missed is re‑syncing the digital time after setting the analog hands.

What maintenance will the 200 m water‑resistant quartz watch need over time?

The mineral crystal and resin case resist shocks and scratches; the quartz movement requires a battery change every few years, and the buckle clasp or strap may need replacement after extended wear.
