Born from the breakthrough idea of a hollow structure. The case employs a hollow structure in which the module is "floated" to protect it from shocks. A full urethane bezel provides all-directional enclosure to prevent direct shocks from striking the glass and buttons. And cushioning material provides extra protection for the key parts such as the crystal oscillator inside the module. These and other shock-resistant technologies, exclusive to G-Shock, are spread generously throughout the body and the module interior to raise toughness to the highest levels.

If we tried to absorb shocks simply by encasing the module with urethane resin or other such materials, the case would grow to immense proportions. G-Shock realizes high shock resistance by supporting the module inside the case at just a few points, thus creating a situation as if the module were floating in air.
