The Casio G-SHOCK GA-2100CMD-8ADR brings a sophisticated camouflage treatment to the streamlined GA-2100 series. Finished in gray, this analog-digital model features an original G-SHOCK camouflage pattern with metallic printing, while the dial carries the camouflage motif with a vapor deposition finish for added visual depth. Built around G-SHOCK's Carbon Core Guard structure, it combines shock resistance, 200-meter water resistance, world time, stopwatch, countdown timer, alarms, and Super Illuminator lighting in a slim and lightweight 51 g design. The bezel and band incorporate bio-based resin, while the case uses carbon and bio-based resin materials.
