On a second look i start to wonder................
I´d say this Autavia is a puttogether of Autavia parts.
Hands are totally wrong as said earlier.Autavia dial is an older execution and does not match this thinner type of bezel.
My guess is that this one has the 1st ececution case second edition dial but case is a 2nd execution case which has the thinner bezel.
Correct me if i am wrong.
Here you can see that bezel is not entirely correct:
