I recently went to an AWCI class to build my watch. What an experience for a noob like me!! Highly recommended and worth a separate post.
We assembled a nearly completely disassembled 6497 movement and cased it. I truly love the end-product, and it immediately went to #1 in my collection. I managed to get it super accurate as well with all the values as good as it get's for a 6497!
However, a couple of days later, while I was putting it on, the watch starts ticking really hard, sufficiently so that I hear and notice, it, slows down and ... just stops. A few shakes and it starts working back again.
Needless to say, I was really bummed out and left it on the desk for the majority of the day to observe what would happen, and it worked fine throughout the day, keeping perfect time. In the evening I was playing around with it, reading on the net about possible causes. I put it down on the nightstand and a few minutes later I hear it ticking really, really hard and maybe 10 seconds into that it stops again.
I know it could be a million things, with a noob assembly. Question for the more experienced guys -- what would be your first guess on where to look?
