Watches with tritium illumination elements have been around for a while, and although they glow for a long time, they're much dimmer than traditional phosphorescence
solutions, which are extremely bright but tend to fade quickly. Reactor's new Never Dark line goes for the best of both worlds, with an extremely bright phosphorescent compound called Superluminova backed up by tritium illumination. According to Reactor, the Superluminova can recharge instantly with even the smallest exposure to light and the tritium remains illuminated for up to ten years. You probably have bigger problems than punctuality if you've been in the dark for ten years, but people expecting the unexpected can also expect to fork over $300-$450 for the Reactor Trident, the first Never Dark watch.
