The leading watch designer for Casio Kikuo Ibe founded a project team consisting of just three members whose aim was to realize an indestructible watch. After watching kids playing, he came to the realization that the inside of a rubber ball remains completely unaffected by the impact. His team then developed a watch with a hollow design in which the interior module of the watch is floating. Men’s watches by Casio G-Shock are perfect for everyday use or for sport and leisure activities thanks to their robustness. Falls and knocks are not a problem for the G-Shock watches for men.
