I heard on another forum an experience from another user whose winder magnetized one of their auto watches and messed up the movement. I had never heard this happening before and wasn't aware that it was a risk so am asking the experts here.
Is using a winder, or a certain type of winder, dangerous for the watches? Is there more or less of a risk using it on batteries vs AC power? Or was his winder on top of a stereo speaker or something similar that might have caused the magnetism?
I just ordered a Tech Swiss model and want to be safe. Thanks!
