Over 25 years ago, Casio set out to design the world’s first fully shock resistant watch. G-SHOCK designers routinely dropped Casio timepieces from the third floor of their building, and studied the specific points of breakage. The result is over a quarter century of immense success, and almost cult-like fandom. G-SHOCK continues to innovate with the latest technological features, wrapped in the toughest construction available.
