Solar-Powered G-Shock for Active Users

The Casio GA-B2100FC-1A is a men's sports watch built with a carbon composite case and resin strap. Solar charging keeps the caliber 5689 running without battery changes. Bluetooth mobile link connects the analog-digital display to a phone app. Water resistance to 200m suits swimming and surface water sports.

Thermals Noise and Power Draw

Solar movement eliminates battery replacements and draws power from ambient light. The mineral crystal protects the black dial with index markers. No audible alerts or mechanical noise are specified in the product data. Carbon composite construction keeps the 45.40mm case lightweight on the wrist.

Sustained Load Behaviour

The watch maintains timekeeping and connected functions during extended outdoor use. 200m water resistance holds under continuous immersion pressure. Solar charging supports uninterrupted operation over long periods. Resin strap and buckle clasp remain secure through repeated exposure to sweat, salt water and UV light.

商品問答

How do I pair the GA-B2100FC-1A with my phone and which step do people miss?

Install the Casio Watches app, enable Bluetooth on the phone, then hold the watch button to enter pairing mode; the step most skip is granting the app location permission, which is required for the Bluetooth link to complete.

What part will need replacement first on the GA-B2100FC-1A?

The rechargeable solar cell inside caliber 5689 typically lasts many years; after that the resin strap will show wear before the carbon composite case or mineral crystal.

At what depth does the 200 m rating stop being safe for the GA-B2100FC-1A?

The 200 m water-resistance covers swimming and surface sports; it is not rated for scuba diving, so the limit appears once you descend below recreational snorkelling depths.
