Casio's G-Shock lineup just got more official with its new collection of military-inspired watches. The olive green timepieces tackle some of the series most desired features: shock/water resistance, world time functionality for up to 48 cities, and 24-hour formats. Difference here? These limited edition tickers include the manufacturer's Tough Solar technology, recharging the device from any light source. Chose from three different models: GR7900KG-3, G5600KG-3 and G6900KG-3. Ten-hut!
