Swing the weight, yeah let's oscillate... Nah! use those teeth and go around, go get the Jet... link

e108 Stephen Looked like the Jet action was a lot smoother. The half rotor seemed to want to almost flip over. Why did Citizen discontinue the Jet?

I'm no geometry genius whatsoever but wouldn't the larger jet wheel increase the amount of leverage needed to wind the movement?

The spinning weight concentrates all it's energy at the center while the ring can only apply it's forces to the gears that are much farther from the center. I guess the Citizen designers took all this into consideration when they designed the system. But maybe that is part of the reason Citizen switched over to the more conventional auto winding rotor scheme...
