lobsterI believe that the majority of watches with Tritium are made in Switzerland by MB Microtec. I've read rumors that there is a place in China manufacturing tritium tubes, not sure how true that is.
JakeRobertsPossibly, though I suppose the tubes are technically manufactured by Trigalight, and thought that many of the tritium watches were made by Traser, both companies being subsidiaries of MB Microtec. I can't remember where I read that, or if my memory is 100% correct (I'd be curious to know more.)
