Somewhere in the mid 50ies... I would say 1955 / 56, with the Cal 215.
Now, to know if and how Patek took an inspiration for their Cal 240, that is another question. I have no answer here.

Hello there.
You have hit a very, very interesting spot and still up to date topic of the watch world!
First of all: Piaget 9P is a manual movement, not an automatic.
I trust you mean the calibre 12P?
In 1954, eleven months before Universal Geneve, a watch company called Büren patented the micro rotor movement.
Universal Geneve and Paiget had to pay Büren a licence fee to use it!
Piaget's P12 was introduced in 1959.
Just recently Piaget paid homage to its 12P 50iest birthday by releasing the 1208P.
Patek came late, very late with its calibre 240.
But the 240 came with some extra titbits: with two ball bearings in the rotor/winding system and the Gyromax balance wheel.
Another very, very interesting and TOP micro movement comes from Chopard: the L.U.C 1.96!
Any serious watch fan will be ecstatic by these letters and numbers, such a great and beautiful movement it is.
Most recent development: Panerai's P.4000 micro rotor movement from 2014.

I knew UG did it quite early, but I was not sure it didn't exist before.
Thanks for this very interesting information, Count.

Know that this topic is on the radar again: I like the idea to focus on micro rotor movements as another theme for a watch collection.
There are some very nice ones out there ...

Hi Jim
that is a very good idea and "shame on us" that we did not come to such a logical conclusion.
But, in all fairness, it will be a big task as there are so many calibers from so many manufactures if it should be a comprehensive one.
To start with micro rotor movements is a good idea.
On the other hand discussing each case individually has also its appeal and has more the "character of sharing", passing the information from one watch fan to another watch fan.
The managers of this site have to decide on this one
