Watch Movements

earlu Swiss watchmaker around 1910 - 1940 period perhaps I have a 18K gold watch with diamonds and movement signed Fred Kaufman, Switzerland, 2 fixed positions, all info is welcome.

I only found information on a German type, Friedrich Kaufmann, who lived at that time (1785-1866), and made complex mechanical devices. He built "The mechanics trumpeter" ( http://www.deutsches-museum.de/sammlunge ... ). This instrument is a real PLC, which produces natural sounds of the trumpet.

Never heard of him, but I'll take a look. A little patience.
No, nothing. I looked at sites in Switzerland and there is nothing their.
At least I tried.

Try googling his name and his watches.
