What is the worst thing you've done to one of your watches? We all do dumb things every once in a while and accidents do happen. For me, it was leaving the crown unscrewed on my Fortis Flieger. I just picked it up that morning, wound it up, set it, and forgot to screw it in. This was in the middle of summer and it was inside. I keep my house around 67 F during the summers and in Arkansas it gets really hot and muggy out. I got to the office, parked my car, looked at my watch and it was all fogged up inside. That's when I noticed that the crown was unscrewed.
I had to work the rest of the day, so I went inside, left the crown unscrewed and put it by the AC vent. I went home and did the same, tried a hair dryer, but the next day, I could see that the damage was done. There were water droplets on the crystal. The lumed hands and dial looked corroded. The worst part about all of this is that I just had the watch serviced 2 weeks prior and was so happy to have it back.
Anyway, I left the watch for over a year before finally getting it repaired. The internals were okay and Fortis repair says that there was no rust. The repair bill was a little hefty because I had to replace the dial, hands, and they recommended a regular service (again!). I get it back this week and I can't wait.
So let's hear your stories!
