The Casio G-Shock GA-B2100 is the solar and Bluetooth version of the octagonal 2100 line, with a slim 11.9 mm carbon-core case and 200-meter water resistance. Tough Solar removes battery swaps, and Bluetooth links to the CASIO WATCHES app for automatic time correction. At 52 g it wears lighter than most full-size G-Shocks, though the analog hands and small digital window take some reading. It suits people who want a rugged everyday watch with smart timekeeping and no charging routine.

Owners treat the GA-B2100 as a tough, light everyday watch and value the solar charging and Bluetooth time sync. The main complaints are the busy analog-digital dial and the mineral glass.
The G-Shock GA-B2100-1AER is a shock-resistant analog-digital watch from the 2100 Series. It has a carbon and resin case and bezel, a resin band and mineral glass. The case is 11.9 mm thick and the watch weighs 52 g.
It runs on Tough Solar power and has 200-meter water resistance. Bluetooth links it to a smartphone through the CASIO WATCHES app for automatic time adjustment. A hand shift feature moves the hands out of the way so the digital display is unobstructed.
A double LED light covers the face and the digital display backlight, with a Super Illuminator and Neobrite luminous markings. The watch also has world time, a stopwatch, a countdown timer, five daily alarms and a full auto-calendar.
