- Is the GA-2100-4A good for swimming?
- Yes. It is rated to 20 ATM (200 m), so swimming, snorkeling and showering are fine. It is not a dive computer and the buttons should not be pressed underwater.
- How does it compare with the standard GA-2100?
- It is the same watch in a red colorway. Movement, size, water resistance and functions are identical, so choose on color rather than specs.
- Does it need a battery?
- Yes. It runs on a standard quartz battery, typically lasting around three years, and there is no solar charging like on G-Shock Tough Solar models.
- Is it too big for a small wrist?
- No. At roughly 45 mm across and under 12 mm thick, it is one of the slimmest G-Shocks and wears well on wrists that find larger models bulky.
- Does it have Bluetooth or app support?
- No. Time, alarms and world time are set with the buttons. If you want phone sync, look at the G-Shock Move or GBD-200 lines.
- What is in the box?
- The watch, a display box and paperwork. No spare strap or tools are included.
