The Toughest Watch of All Time. Born from a dream of "creating a watch that never breaks." In 1983 a CASIO engineer won the battle against the laws of nature. He designed a watch that can withstand a 10m drop, be frozen in a solid block of ice, is hammer shock resistant, 200m water resistant, vibration resistant and anti-magnetic and will still function. The name G-SHOCK has become a byword for independence and pushing the limits and holds the Guinness World Record title for heaviest vehicle to drive over a watch at 24.97 tonnes. Never Give Up.
