I got this in the early 90's when the Tritium watches first started getting public attention. I think it was from an ad in Motor Trend or Road & Track magazine. As posted above, the band was a weak link; Only lasted a year. After the 2nd year, the second hand popped off and would jam the minute hand from moving. At about the same time, the face started fogging up with condensation. I never dived or swam with it- Just a shower in the bathroom every morning. But the tritium still glows!
