Piaget, the watchmaker’s watchmaker, has once again redefined the meaning of “ultra-thin” thanks to its newest masterpiece, the Altiplano Ultimate Concept Tourbillon—the world’s thinnest tourbillon watch.
In the world of high-watchmaking where thin is never thin enough—look at the ongoing battle between Piaget, Bulgari, and Richard Mille for the honours—Piaget caused a furore at Watches & Wonders in Geneva when it unveiled its latest feat to coincide with the Maison’s 150th year anniversary.

Piaget claims that the new Altiplano is “shaped by a quest for elegance and driven by inventiveness”, and while this might be true, it’s clear that the Maison’s high-watchmaking divisions in La Côte-aux-Fées and Geneva are also looking to end the conversation around who owns the ultra-thin watchmaking category.
The new Altiplano pushes the boundaries of horological ingenuity 67 years after Piaget invented its first ultra-thin calibre—the revered 9P—and six years after it presented the world’s then-thinnest watch, the Altiplano Ultimate Concept. Now, with the release of this unrivalled timepiece at just 2mm thick—the same as its predecessor, yet now housing the beat of a flying tourbillon, prized by watchmaking connoisseurs—you can’t help but marvel at its ultra-thin mastery, whether the timepiece is to your liking or not.

In comparison, the Bulgari Octo Finissimo Tourbillon was 3.95mm thick when unveiled in 2020, which seems huge on paper compared to what Piaget has been able to produce. But to craft a watch as thin and groundbreaking as its predecessor, now with an added flying tourbillon complication, the whole watchmaking process had to be revalued and reinvented.
“We did far more than merely add a tourbillon,” says Benjamin Comar, Piaget CEO. “We reinvented everything.”
After three years of R&D, trial and error—and a redesign of 90 percent of the original Altiplano Ultimate Concept components—the 2024 version needs to be held and seen to be believed. The end product certainly isn’t a watch for the everyday watch wearer—although Piaget will tell you otherwise—but in many ways, the company didn’t conjure a timepiece like the Altiplano as a profit-seeking exercise. Instead, overcoming such an arduous and technical watchmaking feat proves that Piaget can master the flying tourbillon in such a whimsical fashion and, in the process, subvert the current state-of-the-art technical principles by making an impactful visual—and technical—statement.
The only question left to ask is, what’s next, Piaget?
