Casio G-Shock SKELETON CAMO Silver Digital Mens Watch GM6900SCM-1G Shock gives its GM6900 series of digital watches a beautiful silver camouflage metal bezel makeover atop a strong resin case. Ideal for the watch collector but also perfect to wear at the beach, the gym, or really any other physical activity. It wouldn't be a G Shock, though, without an array of useful features, which include LCD Display, Shock Resistance, Electro luminescent backlight, Countdown Timer, and 200M Water Resistance. Silver 53. 9 x 49.
