Hello, I recently bought a winder for my smpc. Piccolo winder to be exact. One thing I noticed is that it can be combined with other Piccolo winders, without an extra power supply, using the power of induction. So these winders have some kind of magnetic field on "each square" to provide the power for another winder which touches it. Does anyone know if these winders can actually cause trouble to mechanical watches by its magnetism? I really think that they have thought of that before making it, but I am curious anyway.
