Tritium SWISS - T < 25

[redshirt1957]

Wife bought me a TT GMT II L series and as expected the lume was no longer active. I checked the lume in a totally dark room after 30 minutes so the rods in my eyes would adjust. Kind of boring waiting the 30 minutes. No big deal as the loss of lume gave me some assurance that the hands and dial were original. I realize that Tritium SWISS - T < 25 means the tritium level is less than 25 milliCurie. Now for the reason for this post and I realize I am setting myself up to be seen as a loon.

At night I sit outside and read and am kept warm by two propane heaters. It has been around -2 degrees C at night and I keep the heaters up high. During one of my reading sessions I must have been sitting to close to one of the heaters as the watch got too hot to wear for a couple of minutes. Only thought I had was of cooking the oil in the watch. Went to bed that night and got up around 2:00 am to take care of business and I noticed that the lume was back. Is this possible? I don't think so, but the lume is back for now.
