Piaget Polo 7131 – Rare 18K YG Bracelet, Onyx Diamond Dial

An Architectural Outlier In Piaget History

The Piaget Polo is the definitive jet-set watch of the 1970s and 80s, yet this Ref. 7131 defies the model’s established design language. While the Polo is known for its horizontal “speed stripe” gadroons flowing across case and bracelet, this example features a vertical orientation, creating a strikingly different aesthetic. Extensive research across archival catalogs and sales records has yielded no direct parallels, suggesting this is either a bespoke commission or an extremely limited, undocumented variation.

Such a departure aligns with the practices of Piaget during the period, when the maison frequently accommodated special orders and produced pièces uniques or small-run variations for select clients. Within that context, this watch stands as a rare expression of Piaget’s creative freedom at the height of its design experimentation.

The Vertical Gadroon Construction

In this execution, the polished and brushed 18k yellow gold rows run parallel to the arm, completely shifting the visual weight of the watch compared to the classic look. The transition from the integrated 25mm case into the bracelet is seamless, creating a solid "cuff" effect that appears much larger on the wrist then the original dimensions may suggest. Weighing in at over 134 grams of solid gold, it carries a physical density that serves as a reminder of Piaget’s dominance in high-jewelry watchmaking during this era.

Onyx Mineral Depth and Diamond Accents

The rarity of the case construction is matched by the stone dial. This unit is fitted with a natural black onyx dial, offering a deep, light-absorbing finish that only mineral glass can provide. Unlike standard lacquer, the onyx provides a mirror-like reflection that contrasts sharply against the four factory diamond markers. The combination of the vertical gold lines and the pitch-black stone dial creates a monochromatic gold-and-black aesthetic that feels more contemporary than its 1970s origin would suggest.

Condition and Authenticity

This piece is in good vintage condition and presents with the sharp definition of a well-maintained object. The 18k yellow gold case and bracelet have been polished over time, but the distinct vertical ridges remain well-defined and clear. The onyx dial is in great shape, which is critical for stone dial preservation. There is a minor scratch on the crystal at the 10:30 position. After passing through our test bench, the high-grade Piaget quartz movement is functioning as it should.

The Collector’s "Lost" Reference

This watch works because it is a "museum-tier" find for someone who thought they had seen every iteration of the Polo. It exists completely outside the commodity market of standard vintage Piaget, offering a unique geometry that we simply cannot find elsewhere. It is the correct choice for the collector who values archival rarities and wants a heavy-hitting piece of 18k history that no one else in the room will be wearing. It remains an unapologetic and significant statement of 1970s luxury.
