Casio G-SHOCK Solar Bluetooth Men Watch - Green | GA-B2100-3ADR
Casio G-SHOCK Solar Bluetooth Men Watch - Green | GA-B2100-3ADR upgrades the iconic octagonal 2100 Series with Tough Solar power and Bluetooth Smartphone Link. Its Carbon Core Guard structure, slim profile, Double Super Illuminator lighting, Shock Resistance, and 200-meter water resistance make it ideal for everyday and active wear.
Casio G-SHOCK Solar Bluetooth Men Watch - Green | GA-B2100-3ADR retains the recognizable octagonal form of the original GA-2100 while adding connected functionality and solar-powered performance. Its clean green color and textured dual-layer dial create a versatile design suitable for casual outfits, sports, travel, and outdoor activities.
The watch uses a carbon and resin case reinforced by the Carbon Core Guard structure, providing strength and impact resistance while keeping the body lightweight at only 52 g. The case measures 48.5 × 45.4 × 11.9 mm, preserving the slim and comfortable profile associated with the 2100 Series.
Tough Solar technology converts natural and artificial light into power. Bluetooth Smartphone Link connects the watch to the CASIO WATCHES app for automatic time adjustment, simplified settings, reminders, Time & Place recording, Phone Finder, and access to approximately 300 World Time cities.
Additional functions include World Time across 38 time zones, a 1/100-second stopwatch, a 60-minute countdown timer, five daily alarms, Hand Shift, Neobrite, Power Saving, a battery-level indicator, and Double Super Illuminator LED lighting for the analog face and digital display.
