This is my first post, really psyched to be here.
I'm looking for some information on my dads watch. It's a Piaget ref:9026, marked with Jean-Ete on the caseback and inside of the watch. I can't find any anything about it online and would like to know the value, and how many of the same watches are out there.
Anything you guys could tell me would be great. I'll attach some images below.
