- Is the GA-B2100BEG-1A worth it over the standard GA-2100?
- Yes if you want solar charging and Bluetooth time sync. The standard GA-2100 is cheaper and uses a battery, but you give up the phone pairing and solar cell.
- Does it need charging or battery changes?
- It runs on a solar cell and should not need routine battery swaps. Keep it in regular light, and use power saving if it sits in a drawer.
- Can I swim and shower with it?
- Yes. It is rated to 20 ATM (200m), which covers swimming and showering. Avoid pressing buttons underwater.
- What does the Bluetooth connection do?
- It syncs the time automatically through the Casio Watches app and lets you set alarms, timers and world time from the phone. It does not add notifications or fitness tracking.
- How does the negative display compare with the positive one?
- The negative LCD looks sharper but is dimmer in low light and at angles. If legibility matters most, the positive-display GA-B2100 versions are easier to read.
- What is in the box?
- The watch, a quick-start manual and the usual Casio paperwork. No charging cable is included because it charges from light.
- Where is the Casio G-Shock Bluetooth Solar Bio-Based Band Watch GA-B2100BEG-1A cheapest?
- At CreationWatches, for $134.00, as of our latest check.
