I was riding to work today, and it's not very cold - 10C, when I looked at my GW-1300 and saw that the inside of the crystal had some fog on it. I was a little stunned. It's going to get a lot colder than this - -5 days are typical in winter here, and -10 happens at least a few days a year. The watch is almost brand new, and I'm not worried about the WR, just guessing that the Thai air in there is a little humid. I can read the time through the fog just fine.
But my question is - will this condensation ruin the module? If so, I'm going to need to call Casio about this. Any thoughts? I've read all of the threads in the WUS archive about fogging and I don't think anyone has answered this question.
