Hi experts, I have a Waltham wristwatch from the 1920s. The movement is a 1907 grade 361, and it's basically functionally OK except for the stem. The little split collet that goes into the case and is supposed to keep the stem in place is broken, so my stem keeps popping out into the set position, or just popping out of the movement and case if I try to wind it. Does anybody know anything at all about sourcing a replacement collet, about putting together some kind of a workaround that allows the watch to function, or maybe anything about fabricating a functional replacement? Thanks a LOT in advance...

As some of you probably know, I am right now on the way to build my workshop. This does not mean that it is not possible to think into the future. One of the things that I definitely will buy in the future is a lathe. In addition to whether it should be new or slightly used, there is one thing I have come across that I can't figure out ... Collets. 8 mm Collets, I thought. they were similar but it seems that there are many kinds of thread on them. I am, however, reached forward to it either must be B8 or WW collets. ... Is there anyone who can answer what type of Bergeon Collets are? Is it American-WW or B8?
