G-Shock is a line of watches manufactured by Casio, designed to resist mechanical shock and vibration. Its full form is Gravitational Shock. They are designed primarily for sports, military and outdoors-oriented activities; nearly all G-shocks are digital or a combination of analogue and digital and have a stopwatch feature, countdown timer, electroluminescent backlight and water resistance.

A 10-year battery life, 10-bar water resistance and 10-meter dropping shock resistance.

These were the three 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-SHOCKcontinues to take up challenges beyond the limits of time and common sense.
