Piaget - 1978 Onyx & Diamond / Service
Weighing 170g in white gold, this 34mm model features an onyx dial creating a superb contrast with the white gold case. The bezel is also set with 36 brilliant-cut diamonds. Beneath the dial, the mechanical self-winding caliber 12P is equipped with a micro-rotor for added finesse, and has a power reserve of around 40 hours.
Reference 12336 identifies the model and C20 specifies the type of finish on the case and bracelet.
This watch comes with a 2024 Piaget service invoice (2-year warranty) and a Piaget travel case.
