The GA-B2100 is Casio's modern take on the slim octagonal G-Shock, adding solar charging and Bluetooth phone linking to the classic analog-digital layout. It keeps the carbon-core case, 200m water resistance and shock resistance that made the line popular, while the Tough Solar cell and Bluetooth time sync remove the usual battery worries. It suits people who want a tough everyday watch with phone-assisted accuracy and a cleaner, smaller profile than the chunky 2100-series predecessors. Against rivals like the GA-2100 it costs more but adds solar and Bluetooth; against smartwatches it trades apps and notifications for battery independence and near-indestructible build.

Owners generally rate the GA-B2100 line highly for its slim case, solar charging and Bluetooth timekeeping. Common complaints focus on legibility of the analog hands and LCD, and on the resin strap feeling basic.
