Product Description G-Shock is the ultimate tough watch. It was born fromdeveloper's dream of "creatingwatch that never breaks." Guided by"Triple 10" development concept, the design teams soughtwatch with 10-meter free-fall endurance, 10-bar water resistance and10-year battery life. Attime when it was commonly believed that watches were breakable items, G-Shock's development representedchallenge to common sense. The number of experimental prototypes built for endurance testing reached over 200. And the structural development and parts improvement took approximately two years. Afterlong, hard process of trial and error, G-Shock was finally launched.shock resistant structure that overturned conventional thinking about watches was realized through breakthrough thinking, including the ideas ofhollow-structured case, all-directional protective covering and the use of cushioning material to protect
