Hi
May be someone can help me on this.
I've serviced an eternamatic 1000 movement 1489K automatic.
The watch work perfectly when there is no automatic weight attached like in picture 1
But when I tight the screw of the weight on his axe (in red on the picture) the balance stop very like something was preventing the movement to run run freely the balance re-start normally when I unscrew this screw
How is it possible there should be no interaction between the automatic bridge and the train of wheel ?!?
I post some photo of the movement
Thanks
