Can automatic watches be damage by the magnetic motor inside a watch winder?
No, automatic watches and their movements are not affected by the magnetic fields generated by the watch winder motor. This magnetic field is so small that it has no bearing on the watch and its movement. Furthermore, all modern automatic watches are made up of non-magnetic material such as titanium, brass, stainless steel, etc. Consequently, they are non-magnetic and unaffected by close proximity to magnetic fields.
