Since the problem is more common with Miyotas, here is another approach.
A friend had the same problem and asked me if I could take a look. In this case, the glue unfortunately came off again after a few days. So I decided to try to laser rotor and bearing together. This is a bit fiddly, but works with a little patience, a good laser and proper magnification.
Here is a picture of how the whole thing looked afterwards. Don't be surprised about the milling on the left and right, that was from another attempt that didn't work - so this was just a proof of concept. Worked very well, rotor and bearing are now well connected again.
So if the rotor on your Miyota comes loose, ask your watchmaker if he happens to have access to a laser.
