- Is the GA-2100SU-1A good for swimming?
- Yes. It is rated to 20 ATM (200 m), so swimming, snorkeling and showering are fine. Casio does not rate it for scuba diving.
- How does it compare with the standard GA-2100?
- It uses the same slim case and module. This SU version adds a green-accented dial and a different bezel finish; functions and size are the same.
- Does it need a new battery?
- Yes. It runs on a standard SR726W cell with no solar charging. Casio quotes roughly three years of battery life.
- What is in the box?
- The watch with its resin strap, a manual and the usual Casio warranty card. No charger or extra strap is included.
- Is it too big for small wrists?
- It is one of the smaller G-Shocks at about 45 mm across and 11.8 mm thick, so it suits most wrists. Very slim wrists may still find it chunky.
- Can the hands be read in the dark?
- The hands and hour markers have luminous paint, but the LED light is weak. Many owners use a phone or lamp in full darkness.
