I'm not sure I see it...
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, similar to a double pendulum. Even if they didn't, I'd expect the SW to become a buffer, that is start to swing back before the PW does, sapping some inertia and therefore decreasing winding force. In very small movements, the SW might move without the PW moving at all, converting it all to heat.

If I understand it well, this is a brilliant idea! Well done! Of course...
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...

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...
A movable mass at the line of centers....
Hello sonseik, My thought process says that without increasing mass of the oscillator, there can be no advantage.
Still looking...
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...
I think it's a "jogging" effect.
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.
Perhaps...but then you need to contend with...
...the points that aaron and Don make.
I'm with you on this one Don
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
