There is some "hard core" repairer watchmaker who is willing to make parts by himself...
.. but mostly he does old pocket watches and such, but does wrist watches, too.
Be prepared to pay a few hundreds cost, though. Very skillful man. Want to try? Let me know!
Best,
Ken
PS: What I really wanted to tell people is, while the "street watchmakers" are typically good, if not better than, the brand service center, the brands are stopping supplying parts to outside the service center - in that sense, the parts are drying up outside the service center which we cannot fully trust today, as we see in the comments from many others here.....
