In 1983, Casio launched the shock-resistant G-SHOCK watch. This product shattered the notion that a watch is a fragile piece of jewelry that needs to be handled with care, and was the result of Casio engineers taking on the challenge of creating the world's toughest watch. Using a triple-protection design for the parts, module, and case, the G-SHOCK offered a radical new type of watch that was unaffected by strong impacts or shaking. Its practicality was immediately recognized, and its unique look, which embodied its functionality, became wildly popular, resulting in explosive sales in the early 1990s. The G-SHOCK soon adopted various new sensors, solar-powered radio-controlled technology (described below), and new materials for even better durability. By always employing the latest technology, and continuing to transcend conventional thinking about the watch, the G-SHOCK brand has become Casio's flagship timepiece product. G-Shock and Baby-G Brand G-Shock represents the inner force that's within all of us and it's with this inner force that G-Shock was developed more than two decades ago. Two engineers, with a vision to create the ultimate watch, assembled a rogue team of engineers and named their mission, "Project Tough." Through perseverance and unusual testing methods, such as throwing prototypes out the second floor bathroom window to the asphalt below, they developed the first G-Shock in 1983. This watch was able to withstand their then benchmark of "Triple Ten" criteria, namely 10 years of usage, 10 atmospheres (water resistance) and a 10m fall (shock resistance). Today more than two decades later, G-Shock watches have exceeded the designers' original benchmark and pushed the limits of what a watch can endure. With 200M water resistance & shock resistance at the heart G-Shock's strength and numerous technological advances such as Tough Solar Power and Atomic Timekeeping, you'll have no doubt why G-Shock is called the Toughest Watch in the World. All G-Shock and Baby-G watches are shock resistant. Their unique shock absorbing structure supports the module (inner brains) as if it were floating in air. All G-Shock watches are 200M (20 bar or 660 ft) water resistant. Baby-G watches are 100 to 200M water resistant depending on the model. All G-Shocks use mineral glass for added toughness. Baby-Gs are either mineral glass or plastic glass depending on the model.
