Brand introduction

G-SHOCK established a new concept of toughness in watches. It all began with the passionate belief of its developers in creating a watch that would not break even if dropped, a seemingly foolhardy challenge that overturned conventional wisdom at the time. After more than 200 prototypes and roughly two years of work, the shock-resistant structure was finally completed. This was the birth of the technology that forms the core of toughness. Since then, G-SHOCK has continued to evolve endlessly, pursuing even greater toughness in every aspect: structure, materials, and functionality.
