Born at a time when watches were generally considered fragile instruments, Casio G-SHOCK began as the dream of a young engineer, who wanted to create "a watch that doesn't break, even when dropped."
That engineer was Kikuo IBE, Casio's head of watch design at the time.
Project team tough was formed in 1981 with just three members to realise IBE's vision. They began their efforts targeting a “Triple 10” concept: 10-metre dropping shock resistance, 10-bar water resistance and 10-year battery life.
Achieving their target turned out to be unimaginably difficult. Exhausted both physically and mentally after months of hard work, they began to fear that the project was approaching a dead-end.
It was just at this time that IBE observed some children playing in a park. “No impact reaches the interior of a bouncing rubber ball,” he thought. This observation led the team to develop a watch with a hollow structure with the module suspended inside.
After more than 200 experimental prototypes had been produced, a shock-resistant structure was achieved. The first G-SHOCK, the DW5000, was launched in 1983 some two years after the start of development. G-SHOCK has followed a path of unique evolution ever since, while continuing to retain this basic inherited structure.
To remain unchanged. To remain invincible.
Today as G-SHOCK prepares to celebrate its 30th anniversary, the tough, fiery spirit ignited by IBE's passion burns on, blazing even higher.
This proprietary G-SHOCK system for analogue movements combines multiple motors with an electronic crown structure for joint operations of various functions. It responds to pilots requirements for both multi-functionality and operability.
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.
Developed in pursuit of even greater durability, this innovative reinforced structure is highly resistant to dropping shocks, centrifugal gravity and vibrations. A wide variety of internal and external anti shock technologies, ranging from shock absorbent materials and aluminium washers to a quick lock mechanism, have been adopted.
A 10-year battery life, 10-bar water resistance (approx 200m) and 10-metre dropping shock resistance.
