Piaget - Piaget Protocole Onyx Stone Dial (Ref. 9154)
Model: Protocole
Movement: Manual
Year: Circa 1970s
Contents: Watch Only
Case: The 25mm case is unpolished. We believe this is a very early example of the Protocole because of the caseback. This is because the reference number is not on the case back and also the caseback snaps on without screws.
Dial: The Onyx stone dial is in perfect condition. Anything seen in the photos is just dust on the crystal.
Strap & Buckle: The original strap and buckle.
