Eta 2970-1 rotor mount stops watch

[Dmitry]

Hello,

I am working on a eta 2970-1 and as soon as I screw down the rotor, the watch stops.

The watch runs great without the automatic bridge, when I attach the automatic bridge, it continues to run well, but as soon as I attach the main rotor the watch stops.

Can anyone please share schematics or pictures of the automatic bridge?

I have looked up a few pictures online and it looks like I have assembled the bridge correctly after cleaning, but the fact that the watch stops as soon as the rotor puts counter pressure on the bridge, points me that there js something wrong with the automatic bridge.

Thank you.

Here are the pics of the bridge. Looks correct, but as soon as I screw on the rotor, the watch stops.

Pics.

Might have figured it out.

I have been working on this watch for a while and since I got it as a non runner in a terrible shape, there was no guarantee that parts were proper.

I think the main screw that was used on the rotor was too long, so it was stopping the main train.

As soon as I fished out a much shorter and larger headed screw, things were good again.

Please celebrate with me.
