Panerai Ferrari chrono movement swap …

[23Zen23]

One of my Pam Ferrari have winding wheel problem and just think to swap movement to gen vj/eta .
First question it is 7753 or 7750
( I am thinking that it is 7753).
Second it can be just swap to gen like ETA 7753 ?anybody had have experience ? Or it is more tricky that it looks like at first look?
Anyway those Ferrari watches are so good replicated and I was thinking to put gen non decorated movement to have 99%of gen one feeling.
So any experience and any suggestion ?
