- Does it need a battery change?
- No. Tough Solar charges from light through the dial, so it runs without routine battery swaps. Keep it in light regularly and use power saving if you store it.
- How does it differ from the standard GA-2100?
- It adds Tough Solar charging and Bluetooth mobile link for automatic time adjustment, world time and phone finder. The case shape and analog-digital layout are the same.
- Can I swim with it?
- Yes. It is rated to 200 m water resistance, which covers swimming and snorkeling. Avoid pressing the buttons underwater and skip deep diving.
- What does the Bluetooth link do?
- It syncs time from your phone, sets world time, logs a time-and-place reminder and rings your phone. It works through the Casio Watches app.
- How big is it on the wrist?
- The case is about 48.5 by 45.4 mm and 11.9 mm thick, so it is wide but flat. Most wearers find it lighter and less bulky than full-size G-Shocks.
- What is in the box?
- The watch, its resin strap and the usual Casio paperwork. No charging cable is needed since it charges from light.
