hey, Do any watchmakers or collectors here know if a balance complete for a 215-1 is interchangeable with one for a 218-2? Thanks!
I don't know the answer to your question, but if it is just the staff that is broken, that is still available for both.
I don't think the parts are interchangeable: http://cgi.julesborel.com/cgi-bin/matcgi2?ref=[^[DXG[F http://cgi.julesborel.com/cgi-bin/matcgi2?ref=[^[DXHUE You may want to inquire at Jules Borel about specific parts like balance wheels and shafts. gatorcpa
