you won't find it with the ETA7753. Get the A7753 and get it serviced. and no, you can't replace it since the dial won't fit.
nice write up. good work.
Just one thing. I usually remove all the keyless to make sure the sliding pinion is correctly positioned with the clutch. Sometimes with the yoke gets out of place the clutch can slip. So always remove all the parts up to the winding pinion and reassemble them to make sure the clutch is engaged.
another myth. Serviced by someone like The Zigmeister the A7750 is as good. The reliability problem with asian movements is the poor condition some of them come. With proper oil and cleaning I don't see anything structurally wrong with the A7750.
there you go

However this is a very very complex process. If you have not done any movement work you just don't start with the 7750. Start with a cheap 6497 first.
