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:)
It’s fine but return the winder and get your money back because it’s useless, just wear it and wind it when it dies
