The GA-B2100 is Casio's octagonal-cased G-Shock, the analog-digital 2100 line updated with Tough Solar charging and Bluetooth phone pairing. A Carbon Core Guard case keeps it slim and shock-resistant, and the solar cell means no battery swaps. It suits people who want a rugged everyday watch with analog hands and app-based timekeeping without paying for the metal-cased GM-B2100. Against the original GA-2100 it adds solar and Bluetooth; against the GM-B2100 it trades steel for lighter resin.

Owners rate the GA-B2100 as a tough, light everyday watch and value the solar charging and Bluetooth time sync. Some find the digital sub-display small and the resin finish less refined than metal-cased G-Shocks.
The G-Shock GA-B2100-1ADR is a shock-resistant watch from the 2100 series. It has Bluetooth connectivity and a Tough Solar charging system.
Tough Solar converts light from any light source into power, so the battery does not need to be replaced. The watch pairs with a smartphone over Bluetooth for accurate timekeeping.
The Carbon Core Guard structure protects the module. It provides shock resistance and allows a compact case. The watch uses classic G-SHOCK colors first used in the G-SHOCK 5600 models.
