It all began with a developer’s dream, to create a watch that wouldn't break even when dropped.

A 10-year battery life, 10-bar water resistance and 10-meter dropping shock resistance. These were the three initial requirements of the “Triple 10” concept that led to the development of G-SHOCK’s shock resistant structure.The rugged shape and robust styling originated with an engineer’s brief calling for an “unbreakable watch.” Since its birth in 1983, G-SHOCK has continued its unrestrained evolution while retaining its unique basic structure.Today, G-SHOCK continues to take up challenges beyond the limits of time and common sense.
