Jokerslye,
Piaget ultra-thin hand-wound movement 9P. Manufactured in 1974.
As you can see from the photo, that watch model was not so rare at that time.
The two-colours gold version was probably less frequently produced but we have no means of tracing the number of pieces produced.
A 5-piece series may be too low production. Import restriction of 5 pieces to your market is plausible.
It belongs to the “Legend on gold bracelet” collection.
