A 10-year battery life, 10-bar water resistance and 10-metre 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-SHOCK continues to take up the challenge beyond the limits of time and common sense.
This innovative, further toughened G-SHOCK structure resists dropping shocks, centrifugal gravity and vibrations. Persistently advancing its evolution, G-SHOCK has broken through yet another boundary in the realm of toughness.
Casio’s proprietary G-SHOCK structure absorbs and repels strong shocks and vibrations. This core G-SHOCK technology continues its perpetual evolution.
Highly detailed calculations based on the weight of each hand are conducted to achieve an optimal balance and assure stable hand movements, even under pressure from powerful gravitational forces.
The G-SHOCK Gravity Defier, centrifugal gravity resistance specifications significantly pass 15G, the maximum level required of cockpit instruments by the continuous acceleration test standards for aircraft equipment (ISO 2669). Tests show that the 1/100 – second stopwatch and other functions operate normally under conditions such as air racing and strong gravitational forces.
αGEL® is employed as an insulator surrounding the module inside the case. This structure prevents damage and operating errors under conditions of violent vibrations.
Vibrations resistance is tested for approximately 10 hours under oscillation conditions reaching amplitudes up to 20mm frequencies up to 1000hz and 20G acceleration. G-Shock is certified as surpassing the vibration endurance test standard (JIS D1601 Class 4A) for in-vehicle parts on 2-wheeled vehicles (vibrations up to 20G).
Textured protective forms are adopted for the case and bezel design. These projections guard the watch against impacts such as dropping shocks from any direction. They prevent damage by easing shocks to the buttons which are connected directly with the module, as well to the glass surface and case back.
The rigid curved structure connecting the band with the case enables the urethane band itself to serve as a shock absorber, preventing direct shocks to the case back if the watch is dropped.
Coating important parts inside the module with cushioning material adds further shock resistance, preventing breakage or improper operation if the watch receives a shock from dropping or other accidents.
