Another seller freebie with a purchased watch. It has an issue with winding. When I got it (as a non-runner) it seemed to not wind and just free spin. I assumed the mainspring was bad. However, after experimenting with it for a while I found that if I wind it really slow while pushing in on the crown, it seems to take a wind. It has now been running for 16 hrs and keeping time. It's beyond my knowledge as to what is wrong, possibly the stem is worn?
