Born from a dream of "creating a watch that never breaks." It was over 30 years ago, a CASIO engineer won the battle against the laws of nature. He designed a watch that would resist centrifugal and impact forces, as well as high water pressure. Since then, the name G-SHOCK has become a byword for independence and pushing the limits.
ECO-DRIVE TECHNOLOGY In 1976, Citizen invented the world's first light-powered analog quartz watch that runs using only light as a power source. This technology, now known as Eco-Drive®, can generate power from any light source -- artificial, natural, and even dim light -- to keep watches running without ever replacing batteries.

REACTOR watches are designed to meet or exceed demanding Swiss standards. Cases are forged from solid stainless steel or titanium. Multiple o-ring seals and water-tight screw-down crowns are used throughout. To ensure that a REACTOR will survive the decidedly non-sedentary lifestyle of our target customer, we developed new standards. Swiss sapphire crystals gave way to the more impact-resistant K1, hardened, high-ceramic glass. An entirely new case-to-band fastening system was devised to keep these watches firmly in place during the worst unplanned events. And we devised the world’s only screw down crown that stays water tight – even when unscrewed. REACTOR truly represents the best of what the world of watches has to offer.
