I have a Howard Miller wall clock with a Hermle 351-030A 8 day Westminster Chime Movement. I purchased it used in 2009 and at that time, the movement had just been cleaned and serviced. After a few years of flawless operation, I started to have problems with the clock stopping shortly after the time train spring was wound. Normally, it would run about 2-3 minutes each time before stopping. I’ve always wound it completely to the stop each time I wind it. Even though I always ensured it was completely in beat, I would often have to restart it a number of times after it had been wound. It could sometimes take as many as 10-12 attempts to restart it after winding before it would continue on its own. Finally, two years ago I wound it and could not get it restarted afterwards no matter how many attempts I made. Again, I always made sure it was in beat. I got to the point where I just gave up on it and let it hang on the wall undisturbed. I figured that the movement needed servicing again and since I couldn’t make up my mind whether to service the movement or replace it with a triple chime movement that I've always wanted to put in that clock, I just turned my attention to other things and left it hang there for what turned out to be 2 years. Just on a whim, I decided to give it a try about a week ago. To my surprise, it took right off on the first attempt and has been running like a champ and without interruption for over 6 days now. It's never stopped once. I had thought that since it had been sitting so long, the movement would have gathered dirt, dust, etc. and probably would run even worse when I tried starting it. Instead, the long rest seems to have had restorative powers of a sort. I'm quite mystified about it. Since it is an 8 day movement, it will soon be time to wind the time train again and I don’t know what to expect this time when I do that. Does anyone here have a possible explanation for what I have been experiencing with this clock?
