It all began with a challenge from a developer who was convinced that it was possible to make a watch that would not break, even in the event of a fall. The Tough project team was born in 1981. The team created over 200 prototypes one after the other over a period of around two years. They finally arrived at an impact-resistant structure. Thus was born a fundamentally robust technology. And since then, G-SHOCK has continued to evolve, striving for greater robustness in every respect, from structure and materials to functions.
