I’m working on an Elgin 18 key wind pocket watch that I bought as a “basket case”. The watch had been badly mangled by someone who had tried to do a repair. I think the watch is missing its dial washer but I don’t know if this model used one and I can’t locate a parts manual for Elgin pocket watches. Does anyone know if the older (1872) S/N 223881, key wind and key set watch used a dial washer?
