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 ?
Maybe someone else can shed some more light.

Peter
