I'm not a specialist, please

Just can see the difference between cal 6** and cal. 5**
If you had the chance to look under the balance wheel, in the ebauche you would see a 6** instead of a 5** therefore i called it a 6**.
And of course i can compare to a Rolex modified Cortebert cal.618 to see that the bridge architecture is different and the 17jewels and 16lignes are the things in common.
If that is incorrect I apologize and hats off.
But you cannot pretend that it looks like a cal.517 or 516 when they are not even similar.
Compare it instead to the Rlx Eaton 514 and see they have exactly the same bridge architecture.
I got your point and ammended the original post.
I dont believe in good or bad sense of humor but mine took me to edit indicating you as the specialist just because i was annoyed by the way my post was suddenly populated with something that i would solve with a pm or call.
This doesn’t mean i do not respect your knowledge (which i do).
Best,
