Bulgari Releases the Thinnest Mechanical Watch in the World

The Octo Finissimo Ultra COSC from Bulgari clocks in at 1.7mm thick.


In the world of watch aficionados, every fraction of a millimeter matters. Bulgari knows this all too well, as evidenced by their relentless pursuit of record-breaking thinness with the Octo Finissimo Ultra COSC. Ticking at a mind-boggling 1.7mm thick, this titanium-clad marvel has snatched back the crown for the world’s thinnest mechanical watch, a title it previously held until Piaget’s AUC model took the lead.

Bulgari’s Octo Finissimo line is no stranger to setting records; it’s scooped up eight world titles in just a decade. This latest achievement, beyond its svelte profile, boasts a COSC certification for accuracy, making it not only the thinnest mechanical watch but also the slimmest chronometer-certified timepiece. Crafted with obsessive precision, the Ultra COSC flaunts a reworked case that accommodates an even thinner sapphire crystal, a mere 0.1mm in width. And the luxury doesn’t stop there: a sleek, automated winding case makes keeping time a breeze with just the touch of a button. But act fast—this limited-edition masterpiece is strictly limited to 20 units worldwide, each commanding a princely sum of $529,000. For those undeterred by price tags, Bulgari’s website is the first stop on the quest for wristwatch nirvana.
