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.

Gravity resistance

To avoid breakage of the watch hands that are required to move in an environment of strong centrifugal gravity, detailed calculations have been made to balance each hand and arrange in the most optimal way. The result is stable hand movement that resists strong gravitational pull conditions.

Centrifugal gravity resistance

We realised the ability to withstand centrifugal forces exceeding the highest level (up to 15 G) is determined by the ISO 2669 steady-state acceleration environmental test, typically used for aircraft equipment. The results from this test confirm that the various functions operate normally under conditions of extreme centrifugal gravity.

Vibration-resistant structure

To absorb vibrations, and prevent damage and malfunctions αGEL®*, a soft gel-like material with silicone known for its superior shock-absorption capabilities, is packed around the module as an insulator. Aluminium band washers and O-rings are inserted to prevent the screws connecting the band and case from loosening due to vibrations.

Testing vibration resistance

Vibration resistance performance testing is conducted by generating vibrations with various magnitudes and speeds of amplitude. Performance testing is confirmed by the Vibration Testing Methods for Automobile Parts (JIS D1601 4 Type A) with reference to the grade (vibration acceleration up to 20 G) required for in-vehicle devices.
