I think perhaps you are getting off on the wrong foot here
You asked for advice but then rant about JLC and then Tudor. We have all had issues with repairs but group griping is not the way WPS works; we are not here to beat up on the manufacture for a problem that is not of their causing.
Let's look at this dispassionately. Mainsprings are readily found in the watch servicing market. You need to take out the old one, measure its length and height and thickness and find a generic replacement. It's not a part that's seen or touched. In any case a decent watchmaker will replace the spring while overhauling the watch. Have you considered why it broke? Could there be other issues with the movement? I suspect so. Probably this service in the aftermarket is $500-800. And they won't do any work you don't want done (within reason).
OR
You can take it to the manufacture and get it serviced the way they do it for the price they charge. One of the reasons it costs so much is JLC have a tremendous investment in tooling and parts to keep all those old watches running. They have more than any other manufacture I have visited (20 or so). Who's going to pay for that if not we who own the watches?

Mainspring Problems

Hello all. Recently, I purchased what I thought to be a fine example of one of my grail watches (albeit minor grail but still a special watch), specifically a Memovox Speedbeat E875, Cal. 916. It is gorgeous and the movement(s) are almost great. I wore it...

You're right that was a bit of a rant. Mostly at Tudor admittedly for a matter of aesthetics. I did have my watchmaker (3rd generation) who said it was a little dirty but saw no reason for the break otherwise. Perhaps I just need to take a breather before...
