I might be wrong, but this really does look like some kind of marriage.
There are obviously some Bulle parts, but the lower pendulum assembly looks like it may come from a Junghans ATO master clock. There is a large gearwheel visible at the front of the movement, which again doesn't appear in conventional Bulle movements.
The wiring looks like it has been retro-fitted and the contact pin seems to be a long way from the fork. So I think it is unlikely that the pawl/crown wheel drive is actually used to move the hands ?
It appears someone has tried to modify how the contacts function I’m suspecting. The top ring seems to be a gyroscope setup along with the addition of 2 false? weight cans above the coil. I’m also wondering if they trying to compensate for too much voltage being used? As I’m sure you know, these run on 1.25 volt or a single cell battery.
Have you tried running the clock yet?
