AUTOMATIC SYSTEM SUPPORT
Attached to the movement directly on the mainplate or on its bridges, the automatic system support is in a way the plate or the frame of the automatic system.
Oscillating weight will be indirectly fixed there as well as the reversers and some other components. During an overhaul, all this part can be treated independently.
Also, for certifications like COSC all this part of the automatic system is not on the movement.
