REACTOR watches are designed to meet, or exceed, demanding Swiss standards. Cases are forged from solid stainless steel. Multiple O-ring seals and water-tight screw-down crowns are used throughout. To ensure that REACTOR could survive the decidedly non-sedentary lifestyle of our target customer, we developed new standards. Swiss sapphire crystals gave way to the more impact-resistant hardened mineral glass. The delicate precision of a Swiss movement gave way to the robust accuracy of Japanese quartz. An entirely new case-to-band fastening system was devised, to keep these watches firmly in place during the worst unplanned events. REACTOR truly represents the best of what the world of watches has to offer.
