The GA-B2100C-9A is the solar-powered, Bluetooth-linked version of Casio's slim 2100 series, dressed in a bright yellow resin case and strap with a black dial. It keeps the octagonal case shape and analog hands over a small digital window, adds Tough Solar charging and phone time sync, and stays at 200 m water resistance. It suits people who want a light, tough everyday watch with a loud color and no battery swaps. Against the original GA-2100 it costs more but adds solar and Bluetooth; against a G-Shock square it is slimmer and easier to read at a glance.

Owners of the 2100 line praise the slim case, the tough build and the solar-plus-Bluetooth setup on this version. Common complaints are the dim negative display and the mineral glass, and some question whether the added features justify the step up from the standard GA-2100.
A nice Casio watch which comes with a yellow strap. Analog hands are combined with digital hands.
