A cool example of Piaget’s mastery of stone dial design, pairing a deep black onyx dial with a matching onyx inlay bezel. Housed in an angular 18k yellow gold case, it’s the kind of bold, design-forward watch that helped define Piaget throughout the 1970s and 1980s.

The 18k case measures 23 x 29 mm and is in great overall condition, featuring a sharp hallmark, engraved reference number, and onyx inlay bezel.

The onyx dial is in mint condition.

The mechanical movement is winding well and running smoothly.

On its original alligator strap, secured by the original 18k Piaget buckle.

Stone dial perfection.
