Less is More: A Deep Dive into Bulgari's Feat in Ultra-Thin Horology with the Slimmest Tourbillon Watch on Earth

Mastery in ultra-thin horology is not a title that is easily earned. It requires a combination of creativity, ingenuity, and an unwavering dedication to pushing the boundaries of what is technically possible. Few watchmakers have been able to navigate this terrain as successfully as Bulgari. With a long history of setting one record after the other, the Italian/Swiss manufacturer has truly carved a niche for itself at the pinnacle of ultra-thin watchmaking.

In the year 2024, Bulgari launched the Octo Finissimo Ultra COSC, the world’s then thinnest mechanical watch, boasting an unprecedented thickness of just 1.70mm. This record was contested later by Chaykin. Pioneering innovation and dedicated craftsmanship have enabled Bulgari to add a fresh accolade to its impressive list in the form of the world’s slimmest tourbillon watch.

The elegance of an ultra-thin tourbillon originates from the complexity of its construction. A tourbillon deploys a rotating cage to house the regulating organ of a watch, its purpose: to counteract gravity’s impact on the regulator. While this technical marvel has been a prestigious feat, Bulgari has embraced this challenge, proving yet again that when it comes to watch connoisseurship, less can indeed be more.
