Hi everyone, I have a Bifora vintage wind up watch, German made. I don't know how to assemble it and no horologist or watchmaker or jeweler that I contacted wants to help. I would really appreciate it if someone could direct me to the proper website, magazine, book, anything so I can fix it and get it working again. I have all of the pieces, my only problem is figuring out how to assemble it. These pics are references, My watch looks just like the one in the picture. I really want to fix it but lack the expertise. Thanks a lot
