Isobrite is the first T100 lightweight polycarbon watch with 10 year battery life, sapphire crystal, two tritium markers on the unidirectional bezel, 200m water resistant watch on the market. The "T" rating measures the amount of tritium in a watch. The higher the rating the brighter the watch will be. All other manufacturers of polycarbon cases have a rating of T25. We guarantee this watch to be brighter than any other polycarbon watch or your money back. The brightness is not the only unique features of this watch that sets it in a class of its own. Please check out the features and you will find this the best lightweight polycarbon watch available period. 2 years warranty. Why do T100 watches last so much longer than T25 watches? The Isobrite T100 watches contain approximately four times the amount of tritium gas as the T25 watches do (i.e.: Luminox, Traser, MTM). The higher volume of tritium gas results in a much brighter visible illumination combined with a much longer life span of illumination. The Isobrite T100 watches will have a life span that is approximately twice as long as the T25 watches. Plus, at 25 years the T100 watch will have the same visible illumination that the T25 watch started out with. By that point the tritium in a T25 watch would have become fully decayed and barely visible. On the other hand, the T100 watch will continue to glow for approximately 50 years.

this T100 watch is much brighter than the T25 Armourlite version
If you want the brightest tritium lume T100 is the best you can purchase, that said some colors appear brighter than others. This watch uses orange tubes (with a pair of blue tubes at the 12 o'clock position). I actually can see it clearly even with eyes not yet adjusted to the dark and tell time immediately. In the middle of the night it absolutely glows and is easy to read, with the only exception being the tube on the seconds hand (which is small, orange, and hard to pick up for me).I traded up to this orange isobrite from an Armourlite T25 with green lume. The green lume is easier to pick up at night, but it is much dimmer and it was only really visible and readable after my eyes adjusted to the dark, however once that happens, I could even pick up the seconds hand vial on that watch.I think the IsoBrite watches look fabulous during the day, much higher quality than the Armourlite I had, I disagree with the other review about brightness, since I can read the time easily day or night without any required eye adjustment. Some divers watch with painted lume are brighter immediately after entering a dark room, but they don't last that long, this watch gets brighter (at least as your eyes perceive it) when your eyes adjust to the dark, but can be read clearly in any situation.

Too Dim
I imagine it's because of the orange color of the tubes, but the orange tritium is disappointingly dim. It is visible enough in absolute darkness, but in dusk/dawn conditions it is too dim. Not what you'd expect from T100
