... and Büren did it before Universal Geneve :-)! You should know this Nico :-) ...
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.
Best
Moritz

A question on calibre.
And Universal Genève did it a bit before than Piaget...
... and Büren did it before Universal Geneve :-)! You should know this Nico :-) ...
That was the question I had in mind. Which manufacture housed the micro rotor first.
I have learned it from Oliver, I must confess my friend :-)!
