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 phone link for automatic time sync and easy alarm and timer setup, while keeping the carbon-core guard case that makes it lighter and thinner than a classic square G-Shock. It suits people who want a rugged everyday watch with analog hands and a digital display without charging it or setting it by hand. Against the non-solar GA-2100 it costs more but ends battery swaps; against a Garmin or Apple Watch it gives up smart features and GPS but keeps 200M water resistance and never needs a charger.

Owners rate it well, calling it a tough, good-looking G-Shock that never needs a battery change. Complaints center on legibility of the dark dial and the fiddly app pairing rather than on durability.
