- How is the GA-B2100 different from the GA-2100?
- It adds Tough Solar charging and Bluetooth sync with the Casio Watches app. The case shape and size are essentially the same.
- Does it need a battery change?
- No regular swap is needed. A rechargeable cell is charged by light and lasts about 18 months on a full charge without further light.
- Is it good for swimming?
- Yes. It is rated to 200 m water resistance, so swimming and snorkeling are fine. It is not a dive computer.
- How accurate is it?
- Casio rates it at plus or minus 15 seconds per month on its own. With Bluetooth connected, the app resets the time automatically.
- What is in the box?
- The watch, a quick start guide and the usual Casio paperwork. No charging cable is included because it charges from light.
- Does it track steps or heart rate?
- No. The Bluetooth link is for time setting, alarms and phone finder, not fitness tracking.
