Our take on the CasiOak G-Shock Men's Watch with Bluetooth and Tough Solar Power GAB2100-1A1

The GAB2100-1A1 is Casio's octagonal CasiOak with two upgrades over the basic GA-2100: Bluetooth Smartphone Link and Tough Solar charging. Light keeps it running, and the CASIO WATCHES app sets the time, adds about 300 world time cities and helps you find your phone. The Carbon Core Guard case is 11.9mm thick and the watch weighs 52g, so it wears slimmer and lighter than most G-Shocks. It suits people who want the CasiOak look without battery changes, though the analog hands and small LCD still take some reading.

About the CasiOak G-Shock Men's Watch with Bluetooth and Tough Solar Power GAB2100-1A1

The G-Shock GAB2100-1A1 is the octagonal "CasiOak" GA-2100. Its shape follows the design of the very first G-Shock. This version adds Bluetooth Smartphone Link and Tough Solar power, which charges the watch from sunlight or indoor light.

The Carbon Core Guard case is made of carbon and resin and is 11.9 mm thick. The watch weighs 52 g. A layered dial gives the LCD extra depth, and a double LED light covers both the hands and the display.

The CASIO WATCHES app sets the time automatically, adds around 300 world time cities and can help you find your phone. The watch is shock resistant and water resistant to 200 m (20 bar).

Questions and answers

Is the GAB2100-1A1 worth it over the standard GA-2100?
It adds Tough Solar and Bluetooth timekeeping to the same octagonal case. If you want no battery changes and automatic time, it is the better pick; the basic GA-2100 is simpler and cheaper.
Does it need the app to work?
No. It runs as a normal solar watch without pairing. The CASIO WATCHES app adds automatic time setting, about 300 world time cities and the phone finder.
How does it charge?
Tough Solar charges from sunlight or indoor light. Keep it in light regularly; a full charge lasts months in the dark with normal use.
Is it good for swimming?
Yes. It is rated to 200m (20 bar) and shock resistant, so swimming and snorkeling are fine. It is not a dive computer.
What is in the box?
The watch, a quick start guide and the standard Casio paperwork. No charging cable is needed because it charges from light.
