Well, I guess it's official. I have a face that stops a clock. I put the movement back in the cuckoo I was working on, and put it on a rigged up test stand. It was ticking happily away. I went away for a few hours, and when I returned, it was still doing it's thing. While I was there, sitting in my chair, I could hear it behind me. I turned around for another look, then it suddenly stopped! I'll have to have a closer look and see what the deal is, but it was an odd experience.
