I have a Junghans J36 alarm pocket watch with a gun metal case. I'm in the process of restoring it. I need technical information on its proper disassembly/assembly. Right now all I can find is sales catalog information (from the NAWCC). Ranfft also has a couple of bits. Anybody know how to take these apart safely? I'm a little hesitant to tear into it. I also need some info on dial restoration i.e., who might be able to restore the dial. Thanks!
