Thanks so much for the contact at GP, a very friendly guy and happy to provide background info on my watch. Very rare to get this kind of help these days.
“The GP 41 movement, based on an AS 1843 ebauche, has been produced in 1968. The other number on the main plate is individual. It was needed to pass the Observatory tests. The ref. is 9086 FA. There were several versions (steel, gold plated and 18k gold). In steel like yours, 500 pieces were made, with different dials. Its retail price here in Switzerland was CHF 380“
