Is the GA-2100WS-7AER good for swimming?

Yes. It is rated to 20 ATM (200 m), which covers swimming and snorkeling. Casio does not rate it for scuba diving.

How does it compare with the standard GA-2100?

It uses the same case, module and functions. The difference is the white color scheme, which is a limited seasonal finish.

Does it need a battery change?

Yes. It runs on a quartz module with SR726 batteries and no solar charging, so the battery will need replacing every few years.

How big is it on the wrist?

The case is about 45 mm across but only around 12 mm thick, so it wears slimmer than most G-Shocks. It weighs about 1.8 oz.

The watch on its white resin strap, a manual and the usual Casio paperwork. No extra strap or tool is included.

Can the white strap be cleaned?

Yes, mild soap and water work on the resin. Stubborn marks and yellowing are hard to remove once set in.

Our take on the Casio G-Shock GA-2100WS-7AER

The GA-2100WS-7AER is a winter-white edition of Casio's GA-2100, the slim 'CasiOak' with an octagonal bezel. It pairs analog hands with a small digital window and packs world time, chronograph, stopwatch, alarms, a date display and an LED light into a 1.8 oz resin case rated to 200 m. Owners like the thin profile and light weight for daily wear, and the white resin shows dirt faster than the black or steel versions. It suits people who want a rugged quartz watch with a streetwear look rather than a dress watch.
