Hey guys. I'm working on getting one of my grandfather's old watches up and running. I've serviced the movement, but the hairspring is badly shaped and I just can't get the bugger running. The easiest solution seems to be to source a donor movement with a good balance (I've had already sourced one on general principle, but that also has a stuffed hairspring). This movement comes is some really crappy Raketa and Sekonda hand winding watches from the 80s(?) and I'm hoping someone has one kicking around in their junk box. Condition is unimportant, provided the balance assembly is good. Photo pulled from the www for reference.
