What are the essential design concept of a watch winder?
There should have no magnetic interference onto the watch, not to magnetizing your watch.
The motion of the winding should not be jerking motion that add on wear and tear on to the watch rotor system.
There more important is the gripping of the watch is good secure enough not to drop the watch!
