Casio Men¡¯s GW6900-1 G-Shock Tough Solar Digital Sport Watch

G-Shock is the ultimate tough watch. It was born from a developer’s dream of “creating a watch that never breaks.” Guided by a “Triple 10” development concept the design teams sought a watch with 10-meter free-fall endurance 10-bar water resistance and a 10-year battery life. At a time when it was commonly believed that watches were breakable items G-Shock’s development represented a challenge 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. After a long hard process of trial and error G-Shock was finally launched. A shock resistant structure that overturned conventional thinking about watches was realized through breakthrough thinking including the ideas of a hollow-structured case all-directional protective covering and the use of cushioning material to protect critical parts.
