- Is the GA2100-1A3 good for swimming?
- Yes. It is rated to 20 ATM, or 200 meters, so swimming and snorkeling are fine. Casio does not rate it for scuba diving.

- The GM2100 has a metal bezel and case and feels more premium. The GA2100-1A3 is lighter and all resin, and uses the same module and features.
- Does it need a battery?
- Yes. It runs on a standard quartz battery, not solar. Casio rates battery life at about three years.
- What is in the box?
- The watch on its resin strap and a manual. No charging cable or extra tools are included.
- Can the hands be read at night?
- There is an LED backlight, but the hands themselves have no lume. Reading the analog hands in the dark is limited.
