- Is the GM-B2100BD worth it over the resin GA-2100?
- If you want a metal look and solar charging, yes. The resin GA-2100 is lighter and cheaper but has no solar or Bluetooth.
- Can you swim with it?
- Yes. It is rated 200m water resistant, so swimming and snorkeling are fine. Casio does not rate it for scuba diving.
- Does it need a battery change?
- No, it charges from light through a solar cell. Keep it in light now and then; a dark drawer for months can drain it.
- What does the Bluetooth app do?
- It syncs time from your phone, sets world time and alarms, and tracks step count. The watch works without it.
- How big is it on the wrist?
- The case is about 44mm across but slim, so it wears smaller than most G-Shocks. The steel bracelet adds weight.
- What is in the box?
- The watch, a steel bracelet, and Casio's manual and warranty card. No charging cable is needed.
