Casio G-Shock Rangeman
Casio´s new G-Shock is a Solar-Powered GPS Watch! The G-Shock Rangeman features the world’s first solar-assisted GPS navigation. The GPS can provide 33 hours of navigation on just one charge, but if the battery dies, 4 hours of direct sunlight will revive the watch’s GPS for an hour. Back at home the watch recharges wirelessly on its power pad. The rugged watch also features a Triple Sensor to measure compass bearing, atmospheric pressure/altitude, and temperature. Other notable features include a sapphire crystal face, 20 bar water resistance, and the ability to operate in temperatures as low as -4 degrees Fahrenheit. check out the video below
