In a total, random stroke of luck over summer this year, I was GIVEN this late-60s Rolex Air King 5500 (cal.1520). It was in reasonable shape for a 50+ year-old watch, but was running anywhere from 20–40 seconds per day fast depending on the position I left it running in overnight. The guy who gave it to me told me that it had been serviced in the past 2–3 years and then left in a dresser drawer. I was fine with it running fast, but was slightly unsure of its water resistance...as such, I left it wrapped inside a clean shirt on my bathroom counter when I showered one day; when I got out, I forgot that it was in the shirt and picked the shirt up — dropping the watch onto the tile floor. I immediately let it run down, and after my next paycheck took it to a well-reputed AWCI watchmaker in my area. For $645 after tax, it got cleaned, oiled, pressure-tested, full service, etc. I asked for the case and bracelet to not be polished, but for the crystal to be. It came back looking stellar; I picked it up on a Thursday afternoon, and wore it Friday and Saturday. Saturday night I was out in a light rainstorm, and when I put the watch on Sunday morning, it fogged, and I noticed a tiny drop of water on the inside of the crystal. Monday, I took it back to my watchmaker, and he owned the problem, took it back, pressure-tested it again, and fixed the issue with the case tube and crown: I believe he replaced a gasket again and added additional silicone grease. As of now, it appears to be good to go, and running around +3 seconds per day. So I just thought I'd share, along with some images I took on a couple different straps.
