G-Shock is a watch brand by Casio specializing in fashion trend watches.
In the early 1980s, Kikuo Ibe, the lead watch designer at Casio, came up with the idea of creating an “indestructible watch.” After a two-year test phase, and after continuously optimizing the development of the case and various parts on over 200 prototypes, the first shock-resistant G-SHOCK was launched 1983.
The Triple 10 concept, which served as the benchmark, required a battery life of 10 years, water resistance to 10 bar and shock resistance from a drop of up to 10 meters.
G-Shock watches are equipped with battery-powered quartz movements.
