If camouflage on the dial weren't enough, G-SHOCK turns things up a notch this season with the GA100CM by going all-over camo. The new GA100CM collection, from the popular XL GA100 series, features a woodland camouflage pattern for the band, case and dial. Keeping true to G-SHOCK's design ethos of Absolute Toughness, the GA100CM features Magnetic Resistance, in addition to G-SHOCK's renowned Shock and 200-meter Water Resistance.
