The race for ultra-thin supremacy just got a whole lot more exciting — and once again, Bvlgari is leading the pack. Unveiled at Watches & Wonders 2025, the new Octo Finissimo Ultra Tourbillon slices through expectations with a mind-blowing thickness of just 1.85mm, reclaiming the title of the world’s thinnest tourbillon watch from Piaget’s Altiplano Concept Tourbillon (2mm). Limited to only 20 pieces and carrying a price tag of USD$678,000, this featherweight marvel proves that when it comes to pushing boundaries, Bvlgari isn’t just playing the game — they’re rewriting the rulebook.
Of course, this kind of mastery didn’t happen overnight. Bvlgari has been obsessed with shaving down millimetres since 2014, stacking up world records with releases like the thinnest minute repeater (2016), the groundbreaking Octo Finissimo Automatic (2017), and the slimmest perpetual calendar ever seen (2021). As Jean-Christophe Babin, CEO of LVMH Watches and Bvlgari, put it best, “each record has been a stepping stone. It’s not just about crossing barriers — it’s about completely redefining mechanical watchmaking.” With the Octo Finissimo Ultra Tourbillon, they’re not just breaking records but casually obliterating them.

With a diameter of 40mm, this watch presents a clean, focused look featuring a two-hand display. It showcases rhodium-plated hour and minute hands against a sand-blasted brass background, finished with a dark anthracite DLC coating. The integrated titanium bracelet, featuring a microbead-frosted finish, complements the case’s slender profile with an impressive thickness of only 1.5mm. Despite being thinner than a coin, the Octo Finissimo Ultra Tourbillon still makes a striking impression.
Beneath the sleek surface lies a world of technical mastery. To achieve something this radical, Bvlgari secured eight patents, covering everything from a differential display system to a revolutionary crystal mounting technique. Even the bracelet design received its own patent.
One of the most critical innovations was combining the case middle directly with the main plate, a move that not only saved valuable microns but also provided the entire structure with added strength without sacrificing the paper-thin profile.
Beneath this record-breaking watch beats a tungsten carbide main plate, forming the backbone of the mechanical movement. Two flat, stainless steel crowns — one positioned at 8 o’clock for winding and the other at 3 o’clock for setting the time — protrude like futuristic controls, adding a touch of sci-fi charm to the overall design. Everywhere you look, the attention to detail is staggering: a polished sloping bezel, rhodium-plated tourbillon components, and intricate geometric engravings on the ratchet bring even more flair to this technical marvel.
As Fabrizio Buonamassa Stigliani, Bvlgari’s Product Creation Executive Director, explained, “the goal wasn’t just thinness — it was about achieving precise execution while honoring the distinctive aesthetic codes of the Octo Finissimo line.” In the Octo Finissimo Ultra Tourbillon, Bvlgari didn’t just break another record — they created a mechanical masterpiece that is as visually arresting as it is technically groundbreaking.
True to Bvlgari tradition, the Octo Finissimo Ultra Tourbillon draws inspiration from the coffered ceilings of ancient Roman architecture, specifically the Basilica of Maxentius and Constantine. This rich heritage informs a bold octagonal design for the watch, but the true magic unfolds inside. Powering this record-breaking beauty is the BVF 900 calibre — a hand-wound movement that beats at 28,800 vibrations per hour (4 Hz) and provides a 42-hour power reserve. Compared to last year’s BVL 180 COSC-certified movement, this one sacrifices a touch of runtime (and skips official certification) to accommodate a full-blown tourbillon — adding only a hair-thin 0.15mm in thickness; truly engineering at its most extreme, without a doubt.
Sure, it might not match the specifications of the previous Ultra COSC regarding power reserve, but let’s be honest: when you strap the world’s thinnest tourbillon to your wrist, you’re not exactly nitpicking — you’re flexing. And frankly, you’ve already won with something this breathtaking on your arm.
Are you thinking of adding one to your collection? You’ll need more than just deep pockets — only 20 Octo Finissimo Ultra Tourbillon examples exist. And if your authorized dealer hasn’t already called, best of luck getting a hands-on one of them.
On the bright side, Bvlgari also released the Octo Finissimo Skeleton 8 Days at Watches & Wonders 2025, a stunning titanium piece that is somewhat more accessible — and still very much part of the Octo Finissimo legacy.
