-Shock watches have shattered the notion that a watch is a fragile piece of jewelry, and should be handled with care. Designed to resist practically everything, G-Shock watches offer extreme durability and remain unaffected by strong impacts or shaking. By always employing the latest technology, G-Shock continues to transcend conventional thinking about the everyday watch. Two engineers, with a vision to create the ultimate watch which would then become the G-Shock, assembled a rogue team and named their mission, Project Tough. Through perseverance and unusual testing methods, such as throwing prototypes out the second floor bathroom window to the asphalt below, they developed the first G-Shock watch in 1983. This watch was able to withstand their then benchmark of Triple Ten criteria, namely 10 years of usage, 10 atmospheres (water resistance) and a 10m fall (shock resistance). Today more than two decades later, G-Shock watches have exceeded the designers original benchmark and pushed the limits of what a watch can endure. With 200M water resistance & shock resistance at the heart G-Shock s strength and numerous technological advances such as Tough Solar Power and Atomic Timekeeping, you ll have no doubt why G-Shock is called the Toughest Watch in the World.
