I don't know of any list - that would actually be a very useful thing. The only thing I can suggest is that you contact Omega in your country (for you this would be contacting the service center in NJ because that's where all the parts are shipped out of and where the training happens), and asking them if a specific watchmaker you are thinking of using has a parts account.
I really don't know if they will share that information, but it's worth a try. If you do this, let us know if they confirm it or not.
