I have a 342 movement out of a 2576 that I bought disassembled. The part circled is missing on my 342, I just have a hole. It may have had threads at one time. Does anyone know if this is a screw or dowel?
It's a press fit pin. Most watchmakers will either make one or most of the time will take a long thin screw, screw it into the hole and cut to needed length.
