Any Vintage Piaget Experts (mid 70’s - 90’s)?

Looking for some advice on current/near term U.S pricing/market on a vintage Piaget jewelry watch my father acquired 30-35 years ago. Was acquired as form of debt payment from one of his customers, so he doesn’t know too much about the watch. Has original box. Maybe some papers. He’s probably only worn it once or twice. Been in a safe this whole time. He is the second owner.

I stress U.S market as apparently we have 39% Tariffs on Swiss made watches now, so it helps the watch is already in the U.S.

Details I’ve recently found:


Piaget Protocole. Reference #9154
18k Yellow Gold & Factory set diamond bracelet. Pave dial.
Manual wind. Haven’t opened it up, but my research leads me to believe it is either a 9P or a 9P2 movement. I could be wrong.


I think it is circa mid-80’s - mid 90’s.

 

Just found a sample on Instagram. Same watch.

Appears to be a big and small (him and hers?) version, but I believe the bigger version is advertised as unisex.
