A watchmaker huh? Perfect man to ask my question. I have a Waltham pocket watch that has to be 125 years old, I'd guess. And I have to keep winding it and keep it running. Because if it stops and I have to pull out the stem, I feel like one of these times I'll break it. You have to pull on that stem so hard, practically with all your strength, and that just doesn't seem right. Otherwise it works perfectly. Inpuut appreciated.
