Tritium Keylight

[n2ize]

I've thought about one of those watches, but a useful lifespan of 10 years for a watch that runs $5-800 isn't such a great deal...

I am not entirely sure but, I think some watch companies will replace the tritium tubes on the watch when they go dim. I read on a watch forum that supposedly the "Ball Watch Co." will offer tritium replacement as an option during scheduled maintenance. As with most expensive mechanical watches they require periodic maintenance. Other watch companies may not do this. I would advise anyone buying an expensive tritium watch to see if the manufacturer will replace the tritium when the time comes before buying the watch. Or, just buy an inexpensive LCD watch with an indiglo( R) background light.
