G-Shock GA-B2100-2AER Watch Blue

(2,418 reviews)

With Bluetooth connectivity and a solar charging system, the new GA-B2100 shock-resistant watches take the iconic 2100 series to a whole other level. The Tough Solar charging system effectively converts light from any light source to power the watch - which means no need to replace the battery. The smartphone pairing via Bluetooth delivers accurate timekeeping. Combining the Carbon Core Guard structure, which protects the module and provides both shock resistance and a compact case, with G-SHOCK classic colours first used in the G-SHOCK 5600 models enables you to wear the latest, and the greatest G-SHOCK has to offer. The GA-B2100-2AER model is a subtle blue colour with a reverse LCD.
