Casio G-SHOCK Bluetooth Solar Men Watch - Black & Dark Brown | GA-B2100CT-1A5DR offers a nature-conscious interpretation of the connected GA-B2100. Its black octagonal case is paired with a dark brown cloth strap colored using a dye extracted from coffee, giving the watch a soft earth-tone appearance suitable for casual, outdoor, and everyday outfits.
The band uses CORDURA® re/cor™ fabric, combining durable CORDURA nylon with recycled PET fibers. It is colored using FOOD TEXTILE dye made with more than 90% natural ingredients, repurposing food materials that would otherwise be discarded. Key resin components are manufactured using bio-based resin derived partly from renewable organic resources.
Carbon Core Guard construction reinforces the slim and lightweight case, while Shock Resistant construction, Mineral Glass, and 200-meter water resistance provide dependable everyday durability. Tough Solar technology converts natural and artificial light into electrical power.
Bluetooth® Smartphone Link connects the watch to the CASIO WATCHES app for automatic time adjustment, simplified watch settings, reminders, Time & Place recording, Phone Finder, and access to approximately 300 World Time cities. Double Super Illuminator LEDs illuminate both the analog dial and digital display.
