some hurdles will have to be resolved, as for example the oscillating "counter weight" or "helping weight" will have to be manufactured, what material will be used for instance? but I am sure these engineers would have thought about this anyhow. Good idea... 

Without a simulation to prove me wrong, I'm not sure I see the advantage. Once the weight has finished it's initial swing, when the secondary weight (SW) be immobile relative to the primary weight (PW), I'd expect the relative movements to become chaotic,... 

almost people think that oscillating weight is shaking for power reserve. it is true. but.... actually not shaking well ...because of resistance .... so when watch is moving .....if oscillating weight is not moving ....it make power reserve well..... uder...

Hello sonseik, My thought process says that without increasing mass of the oscillator, there can be no advantage.

I'm still trying to find where the advantage is supposed to come from. I see it as adding a point weight at the point where the second mass is fixed to the first. As this point is closer to the point of rotation of the main weight, reducing the lever effe... 

When the watch is moved, but not enough to cause the oscillating weight to make a movement that actually winds the watch, I think this could break the initial resistance to movement.

...the points that aaron and Don make.

I also don't see where any mechanical advantage is supposed to be derived. -JD

did something in this manner. do not know about efficiency, but spectacular in looking
