Isobrite is the world's first T100 tritium illuminated lightweight polycarbonate watch. Unlike ordinary tritium watches that use T25 tritium illumination, the Isobrite watch uses ultra bright T100 tritium illumination. This makes it 4 times brighter than the competition. The Isobrite Valor 421 Watch features a lightweight polycarbonate face with a sapphire crystal protecting a metallic colored face with matching tritium illumination and crown, chronograph functionality, and a rubber band.
