Mine was made in Berne, Switzerland. What I do not know is the date it was made. The serial number is: 63372
It was my fathers and he gave it to me before he passed. I have carried it for years hunting, and it's a beautiful brass compass, and still works very well.
I thought I would ask here as, there is always someone on this website who has an answer, which I am grateful for.
Hoping someone can help me out.
