The Breguet rotor wrench arrived and finally I was able to to get close to the coupling wheel in question. From the beginning I was suspicious that the coupling wheel is more elaborate then it looks. My suspicions were correct! It is actually two wheels s...
This is also how oscillating pinions work, two different sets of teeth
It's also (rarely) done on normal lateral coupling system, like some of VC's ...
The real mystery
What I really do not understand this arrangement being a really radical solution. In order to accomplish the stacked wheel coupling, they had to redesign several parts of the chronograph mechanism. Not only the coupling wheel bridge, also the coupling yok...
a completely new concept to me - thanks for going the distance and sharing.
I'm kinda curious, what is a watch chop shop? Hard to imagine that gutting a Breguet for the gold in the case would be the best value....unless it's stolen, I guess..
