Isobrite Eclipse ISO201 Black-Blue Watch | Silicone professional series The plastic heart-rate module isIsobrite 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 Eclipse features an all black face true to the name, with white contrast markers for the hours and hands and blue and orange tritium illumination on a polyurethane band. [Details]
