Many people don't know the winding direction of their watch windder when they buy a watch. If your watch is unidirectional, you need to know whether the automatic winding is clockwise or anticlockwise. If the rotation direction is wrong, it may lead to the problem that the watch can not be wound and has no power! If your watch is bi-directional, you can use the method of switching between clockwise and counterclockwise. There are two pictures for you to refer to. There are instructions on the general watch manual.
Direction: CW is to set the optional top chord clockwise, CCW means to rotate the top chord anticlockwise, and the bidirectional top chord can be set to automatic. Take Rolex as an example, it can be wound both clockwise and anticlockwise. Taking Patek Philippe 324 movement as an example, it is CCW that needs to set the meter swing instrument to wind counterclockwise. Both can be bidirectional, and can be rotated automatically in both directions.
I hope this will work for you. In addition, there are two points to pay attention to when using the megger: first, before the watch is put into the megger, it is better to have more than half of the kinetic energy of the watch itself when it is in normal running time. Because the megger is used to maintain the watch's travel time, it may not be able to drive it when it has stopped moving; second, it is to select a suitable rotation mode.
