I wind my manual watches at least one time a month when I don‘t wear them. I have just one perpetual calendar with an automatic movement that I keep running on a winder.
What I would be very interested in - and nobody could answer it so far - if winding an automatic watch manually from time to time does it more harm than keep it running on a watch winder? The feeling of winding an automatic watch manually is different to winding a manual movement.
