At the other end of the spectrum, consider a winder whose spindle turns at ½ RPM, which comes out to 720 revolutions per day as well– just a bit more than needed to keep the same watch wound. This winder keeps the watch turning continuously, 24 hours per day, subjecting the watch to extra torque for the entire period.
