G-SHOCK Technology

Advanced technologies driving the evolution of toughness

An answer has been found to the unlimited toughness toward which G-SHOCK continues its persistent evolution. It is the ideal of robustness, functionality and operability combined with absolute toughness. This ideal is the source of the toughness G-SHOCK is seeking.

Smartphone Link

Coordination with smartphone-powered Bluetooth allows for easy communication between your phone and your watch for easy operation and timekeeping accuracy.
Shock Resistance

Core technologies supporting G-SHOCK’s pursuit of toughness
GPS Signal Reception

Acquires positioning and time information from GPS satellites for fast, accurate time correction wherever you are.
Carbon Core Guard

A carbon fibre-reinforced resin case structure that keeps G-SHOCK tough, lightweight and wearable.
Triple-G Resist

A tough structure built to withstand the three main types of gravitational acceleration. G-SHOCK's unique case-and-bezel form combined with an all-directional guard structure has been built to mitigate impacts and resist dropping shocks. Featuring a hollow case structure to protect the model from external shocks, as well as cushioning protection from direct shocks for key parts inside the module.
200m Water Resistance

Reliable water-resistance specifications in preparation for use under a wide range of conditions
Tough Solar

Tough Solar: Casio’s proprietary solar charging system. Casio’s Tough Solar converts not only sunlight, but even light from weaker light sources, such as lamps, into power for the watch.
Standard Time Radio Wave Reception

A built-in miniature antenna conducts high-sensitivity reception of standard time, carries time information, and corrects your watch’s time automatically.
