111 or 510 ?

[Aventura]

I read recently that a friend of the Forum said that the 111 movement has proved to be a robust workhorse movement, easy to fix and regulate by any decent watchmaker, no need to be a slave of Richemond every time you need to adjust it or clean it etc.
The model 510 is the same but is provided with an in-house P 5000 movement.
It can also be served by any watchmaker or need to carry Panerai for any problem?
I guess being manually winding it could handle any watchmaker specialized but rather ask the friends of the Forum.
What I regret tha Panerai never made manually winding models 312 or 351. There are other models but I do not like cyclops
Thank you.
