Isobrite is the world's first T100 tritium illuminated lightweight polycarbon 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 Chronograph is the best of the Isobrite line with lightweight polycarbonate construction and ultra bright tritium illumination.
