BRAND HISTORY

Piaget 9131 Lapis Lazuli 18k White Gold, 1970s - Hardstone dial. Ultra-thin movement. Geometric perfection.

This extraordinary Piaget, reference 9131 C4, is a sculptural expression of the brand’s elegant boldness in the 1970s — where haute joaillerie met ultra-thin horology. Crafted entirely from 18k white gold, the watch features an architectural case and seamlessly integrated bracelet, flowing effortlessly around the wrist with refined geometry.

Its star feature? A flawless natural blue lapis lazuli dial, untouched and vivid, with the signature flecks of gold pyrite characteristic of this rare stone. Framed by a minimalist white gold bezel and paired with an elegant alpha handset, the effect is deeply refined yet undeniably eye-catching.

Inside ticks the legendary Piaget Caliber 9P, introduced in 1957 as the world’s thinnest manual-wound movement at just 2mm. This technical feat allowed Piaget to pair hardstone dials like this with ultra-slim cases — a hallmark of the Maison's daring innovation.

Piaget

Elegance. That’s the word that echoes through every creation by Piaget. Since its founding in 1874 in the quiet Swiss village of La Côte-aux-Fées, Piaget has always done things with a sense of grace and refinement that feels almost effortless — yet is anything but.

Originally a specialist in ultra-precise movements, the maison rose to fame not only for its engineering, but for making the thinnest mechanical calibers the world had ever seen. What began as a pursuit of slimness became a philosophy — watches that disappear on the wrist, but leave a lasting impression.

In the golden decades of the 50s, 60s, and 70s, Piaget blossomed into a symbol of bold creativity and jet-set sophistication. This was the era of malachite and lapis lazuli dials, intricate gold bracelets, and case shapes that blurred the line between jewelry and timekeeping. Their vintage watches from this time remain among the most artistic and distinctive ever made — unapologetically elegant, wildly imaginative, and deeply collectible.

To own a Piaget vintage watch is to wear more than time. It’s to carry a piece of mid-century glamour, captured in solid gold and stone. It’s to appreciate the rare intersection of haute horlogerie and haute couture.

But beneath the beauty lies brilliance. Every Piaget movement, no matter how thin, is crafted entirely in-house — a testament to their quiet mastery. No shortcuts. No compromises.

A Piaget is for the collector who moves with subtle confidence. Someone who understands that real luxury is never loud — it whispers in gold tones and polished stone, in hand-finishing and harmony.

It’s a vintage watch not just to wear, but to be seen in. Timeless, bold, and eternally refined.
