I am new to watch winders and just purchased a wolf cub, however I have noticed these sporadic jerky movements in the rotation that I have filmed In slow motion, I have very limited knowledge about this so I was hoping someone could help me out and let me know what is causing it and if it is detrimental to my watch, thanks in advance:)
This looks like a wolf winder, yes ?
I have 5 of these winders, and having had watches in them for years, they’ve never caused any damage. I have no idea what you are concerned about, you will get much MUCH more jerky movements just wearing the watch (assuming you do actually wear it).
