I thought the same, got nothing to lose in having a go. I’ve done quite a few quartz anyway. You’re right though, the stepper is totally frustrating, sticking to everything. I have tried spinning it up with my quartz tester, it only ran for a short time and stopped. The movement has been in for over ten years now so I reckon it would be due some attention anyway. I’ve a couple of other things to finish up first, then I’ll have a go.
