The GA-B2100MF-1A is a solar-powered G-Shock in the slim 2100 case, with analog hands over a digital window and Bluetooth link to the Casio Watches app. It adds Tough Solar charging and a step tracker to the classic octagonal design, and the fluorescent accents glow against the matte black resin. It suits people who want a rugged everyday watch with phone-assisted timekeeping and no charging cable. Against the original GA-2100 it gains solar power and Bluetooth but keeps the same mineral glass and resin build, so it is not a step up in scratch resistance.

Owners of the 2100 line praise the slim case, the legible analog-digital layout and the set-and-forget solar charging. Complaints center on the dark digital window, the resin strap feeling basic, and Bluetooth features that only work when paired.
