The GA-B2100 is the solar and Bluetooth version of Casio's slim 2100-series G-Shock, the octagonal case modeled on the original 1983 DW-5000. It adds Tough Solar charging and a Bluetooth link to the Casio Watches app for automatic time sync, world time and phone finding, while keeping the carbon-core guard case and 200m water resistance. It is thinner and lighter than the chunky G-Shock squares, and it competes with the non-solar GA-2100 and with solar rivals like the GBD-200. Owners like the analog-digital layout and the near-identical look to far more expensive watches; the common complaints are the dim, small digital display and the stiff resin strap.

Owners rate the GA-B2100 as the practical pick in the 2100 line: solar and Bluetooth for a slim, tough watch. Praise centers on the look, the light weight and never worrying about a battery. Criticism focuses on the small, dim digital window and the basic strap.
