How do you make a plastic watch tough enough to be called a REACTOR? Make it out of stainless steel. Seeing how tough space-age polymers are dominating the firearms market, we decided to experiment. Step one was finding the right polymer, which we did with Nitromid™, a glass-reinforced polymer with a tensile strength higher than steel. But that was only part of the problem. All plastics have some elasticity, which improves their durability and impact resistance, but really hinders their ability to be made highly water tight. Our solution? A stainless steel core that houses all of the water-tight connections on a watch - crystal, caseback, and screw-down crown. The result is a watch over 50% lighter than an all steel model with the same water-tight integrity but improved scratch and impact resistance. We call that the best of both worlds. And of course, Gryphon features our patented Never Dark® illumination technology, which keeps the watch visible 24/7 regardless of light. For military, public safety, and active outdoorsmen, we don't think you can buy a better watch at any price.
