Movement looks to be in good condition.

Good amplitude, but it’s still a good idea to service the watch as there are traces of dirt and lack of oiling.

Very nice dial patina.

I remove the dial and hands and everything looks very good.

When removing the bridge screens, it’s worth remembering that the first screw is smaller than the rest.

I think last time this watch had a service it was dumped whole in the cleaning machine. You can see a film of some fluid underneath the train bridge.

The old mainspring in the barrel.

The cleaning machine has done a great job and the movement comes out looking like new.

Clean and oiled mainspring in the barrel.

I test that the balance moves freely after oiling the shock jewels.

Clean gear train aligned.

Winding/setting mechanism back together and greased.

Dial and hands go back in place.

Movement back in the case looking great. I also replaced the crown.

Same amplitude as before, but now there won’t be any unnecessary wear and tear. 

The good condition of the dial combined with the patina makes a unique watch.

A very rare timepiece!
