Please share with us what was Under your Xmas Tree!
If my damn computer would like to work with my scan, I could show you what I got.
A supplementary repair notes for the Cal 825 ( Memovox ) which also applies for the Cal 815, since it is the same movement, without the date, though.
Here is a scan I could find in my hard disc. Which will do the work till I repair the link between my scan and my computer:
Up to you, guys!
Best,
Nicolas
