Details
While Reactor’s original Proton set a new standard for analog world time watches, the Proton Never Dark® takes the style to a new level. For easier reading, we’ve simplified the dial by removing the chronograph function, and for true 24/7 visibility, we’ve added our patented Never Dark® illumination system. So now you can know the time anywhere, at anytime, in any light (or no light at all). It’s the only watch you’ll need as you travel the world.
