In 1983, Casio introduced the shock-resistant G-SHOCK watch. This product shattered the idea that watches were fragile jewelry and required careful handling. It was also the result of Casio engineers' challenge to create the world's most robust watch. With a triple-layer protection design for its parts, module, and case, the G-SHOCK became an incredible watch unaffected by strong shocks and vibrations. Its practicality was quickly recognized, and its unique appearance, embodying functionality, made it incredibly popular, leading to explosive sales in the early 1990s. G-SHOCK has since incorporated various sensors, solar-powered radio control technology (explained below), and new materials to achieve even greater durability. By constantly adopting the latest technology and surpassing conventional ideas about watches, the G-SHOCK brand has become Casio's flagship watch product.
