Have you experienced when winding the watch, the crown just returns?
You can't wind your watch.
The possibility that it's the click spring that has broken, is a high possibility
I experienced this with my moonie and after some searching, I found a solution to do it myself.
It's not very difficult, but some skills is needed.
After lying unused for nearly a year, it's nice to have it repaired,eventually.
Will try to explain with some pictures.....
The broken spring
The click springs I orderd from Otto Frei
First the movement has to be removed
Remove the start/stop lever and spring arm - the spring arm first
By removing this screw, you find the click spring
Find a spring that fits and mount in reverse order.
Wola, you have a working moonie
I did also regulate and waterproofed it,so now I allmost have a perfect rep
Next is to freeze the hour counter at six....see this link for more info
Cheers
