All the rotors on this double watch winder operate on a basis of gentle rotation to wind watches. Older generation Watch Winders were programmed to be always on (i.e. rotating without a pause) in an effort to wind the watch as quickly as possible. This can lead to over-winding of a watch and potential damage to the main spring. Gentle rotation ensures a consistent movement over a longer period of time that won't over-wind your watch.
When initially turned on the rotor turns for 1 minute before pausing. The length of the pause is determined by the Turns Per Day setting (a lower TPD setting will mean a longer pause and vice versa) and once it is completed the rotor turns again for just 1 minute. This cycle continues silently for 12 hours, then rests for 12 hours, before beginning again and so on until the dual watch winder is turned off.
If the Direction setting is set to clockwise then the rotor will always rotate in a Clockwise manner; the same principle applies if the Direction setting is set to Anti-Clockwise. However, if the Direction setting is set to the third setting, Alternately Clockwise/Anti-Clockwise, the first 1 minute rotation will be Clockwise, the next 1 minute rotation will be Anti-Clockwise and so on, ensuring your watch gets a balanced, yet gentle, rotation.
