1970s Onyx Mother-of-Pearl White Gold

A stunning 1970s Piaget Protocole dress piece, commanding attention with its cloud-like white mother-of-pearl dial beautifully outlined by a black onyx frame. The 18k white gold rectangular case features elegant slanted corners and finely executed ridging, with the unsigned crown discreetly tucked into the caseband.

The dial is intentionally minimal: black Piaget print contrasts against the iridescent mother-of-pearl, while Swiss appears in white against the onyx surround. Silvered dauphine hands complete the composition, offering legibility without disturbing the balance of the dial.

At just 4.5mm thick, the watch is powered by Piaget’s caliber 9P manual-wind movement, a hallmark of the brand’s ultra-thin dress watches from the era. It is paired with a black lizard strap that perfectly complements the black-and-white, almost tuxedo-like aesthetic, secured by a raised “P” signed 18k white gold buckle.

Elegant and striking — as only vintage Piaget can be — this is not a configuration you’re likely to encounter often.
