Pallweber mechanism: How it works

The IWC Tribute to Pallweber Edition “150 years” is a wristwatch with jumping numerals.
Contrary to the historical pocket watches, in the IWC-manufactured 94200 calibre, the
display discs are powered using a separate barrel. In this way, the flow of power in the
main gear train is unaffected.

I made this model entirely from scratch, just from a few photos of the wristwatch.
You can download the 3D model of this mechanism on GrabCAD: https://grabcad.com/library/iwc-tribu...
There, you can find the SpaceClami CAD model and a fully animated Blender file.
You can appreciate the jumping mechanism when the time changes from 9:59 to 10:00.
