JAoneExactly. WTF?
I have a couple of tritium tube watches, and as a word of caution for the uninitiated, they are underwhelming in brightness. I thought my first tritium watch was a lemon, but soon discovered that is normal. As your eyes adjust to the dark, they appear much brighter. When you wake up in the middle of the night, they are easy to read. And they last all night (well, for 10-15 years or so anyway :-) ) I really wish we could get radium again lol.
