About G-SHOCK

G-SHOCK began with a dropped watch. Casio designer Kikuo Ibe saw a watch break when it fell, and proposed “a durable watch that would not break even if dropped”. The project set itself the “Triple 10” goal: survive a 10-metre drop, resist water to 10 bar and run for 10 years on one battery. The first G-SHOCK, the DW-5000C, arrived in 1983.
