Is the GA-2100K-2AER good for small wrists?

Yes. The octagonal case is one of the slimmest and lightest in the G-Shock range, so it sits closer to the wrist than square models like the DW-5600.

Can you swim with it?

Yes. It is rated water resistant to 200 m, which covers swimming and snorkeling. It is not a dive computer.

Does it have Bluetooth or solar power?

No. This is the standard GA-2100 module: no Bluetooth, no Tough Solar and no step counter. It runs on a battery.

How does it compare with the GA-2100-1A1?

Same case, module and features. The difference is the finish: this one has a translucent blue case and band instead of matte black.

What functions does it include?

World time, a 1/100-second stopwatch, a countdown timer, five daily alarms, a full auto calendar and a dual LED light for the hands and the digital screen.

Will the translucent band turn yellow?

Clear and translucent resins can discolor with sun and sweat over years. Wiping it after wear and keeping it out of long sun exposure slows this.

Our take on the Casio G-Shock Blue Transparent Analog Digital GA-2100K-2AER

The Casio G-Shock GA-2100K-2AER is a slim analog-digital G-Shock in a translucent blue resin case and band. It uses the 'CasiOak' octagonal case shape, which is thinner and lighter than classic square G-Shocks like the DW-5600. It has shock resistance, 200 m water resistance, world time, a stopwatch, countdown timer, alarms and a dual LED light. It suits people who want a tough everyday watch with a streetwear look; the analog hands are small and the negative digital display is hard to read in low light, so it is not the best pick for legibility-first buyers.
