Want to work a little bit harder to read your watch? If you do, Tokyoflash wants to make your dream come true for only $112.67. They're selling a wristwatch called the Active Reactor which looks like something your local Hazmat teamm could make use of. You tell the time but counting/adding up the lights or something like that. It is water resistant though and I doubt you'll find anything like this anywhere soon.more details here.
