I get the impression that most don’t want to touch these. It’s probably cheaper to just buy a new movement and swap it in.

It is much cheaper, if you've ever stripped one down ye'll know why, put this way I've tried 2 now, and neither went back together, 'twas option 3 ....

Bold of you to try! I saw this from KJ2020 a while back and have been afraid of the 7750 ever since. I’m never going anywhere near those movements:

You might find it interesting, and I'm sure this is one reason many rep watchmakers won't touch an A7750. When you simply remove the rotor bridge you open up a nightmare of pieces that are a royal PITA to get back together.

Everything has to be situated perfectly. A stiff spring at A pushes that gear off angle and out of position. A gear beneath B has to mesh with the large gear next to it, and its pivot stay in that tiny hole in the lever. All the other circled parts have to stay in place. Then when you go to replace the bridge, you always knock something out of place.

What an almost impossible ordeal! It's as bad as a DG2813's combined train/barrel bridge with its many spindly and wobbly pivots. I was only able to reassemble the 7750 by taping parts down, replacing the bridge then pulling the tape out. Arghh.
