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 direcrt 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.
