Always a pleasure to service these excellent movements ! I'm not a professional watchmaker, but I'm happy with the result

Before









After

 

It sure is shiny! And creative use of a case holder. Any before and after pictures on timergrapher?

 

Before the cleaning the watch was not accurate, + 5 minutes/24 hours.
Now + 5 seconds.

 

Thanks for posting. Did you replace the mainspring?

 

Also interested to know if you've changed the mainspring. Have the amplitude and error rate changed much?

 

I did not change anything.
I don't have a timegrapher so I don't know the amplitude, but it seems ok. I should buy one.

 

Nice work!
