·The watch is in solid gold (stamps, weight) and runs ... If you have any information, I would be very thankful!

Sorry I can't bring helpful information fot you since I am novice too.
But I like the overall conditions (observatory logo still very sharp even if it is solid gold case, beautiful hands, French case apparently...) Seems it came cheap (traded with drawing?) So if it was mine I would look for a good redialer to have a redone dial consistently with watch ref (which one we will know when you get opened the watch head)...
But that was my 2 cents!
On the side note: hats off to the OP and @X350 XJR for their beautiful vintage cars, especially the convertible one 👍
