Bianchet’s new B 1.618 UltraFino Carbon marks a defining moment in the evolution of tonneau-shaped sport watches. Known for pushing boundaries, Bianchet now becomes the first to successfully integrate a carbon bracelet into a monobloc carbon tonneau case—a feat long considered a technical impossibility. Made from a dense composite of 500 layers of carbon fiber aligned at precise angles, the result is a timepiece that’s ultra-light, shockproof, and scratch-resistant—built for extreme conditions yet refined enough to represent the pinnacle of modern Haute Horlogerie.
At the heart of this featherweight powerhouse beats the UT01, one of the world’s thinnest automatic skeleton tourbillon movements. Measuring just 3.85 mm in height and weighing only 8 grams, this titanium caliber showcases horological innovation at its most elegant. It includes a suspended mainspring barrel, an ultra-thin 2.66 mm tourbillon cage, and a unique winding system. The movement’s visual impact is equally compelling, featuring a Fibonacci-inspired rotor and golden geometric patterns on the bridges, giving the piece a poetic interplay of mathematics, art, and mechanics.
Bianchet’s obsession with harmony is evident in every detail. Inspired by the Golden Ratio, the UltraFino’s proportions flow seamlessly from its curved tonneau case to its integrated carbon bracelet. A palette of color accents—sky blue, red, or white—complements the brand’s signature rubber gasket, while polished chamfers and smoothed edges add a sleek, aerodynamic profile. Despite its avant-garde materials and ultralight build, the UltraFino is water resistant to 5 ATM and engineered to withstand shocks of up to 5000G, making it as comfortable on the wrist as it is capable in motion.
Tested by elite athletes like Esteban Ocon and Grigor Dimitrov, the UltraFino Carbon is more than a design statement—it’s a proven performer. Each piece is hand-finished at Bianchet’s atelier in La Chaux-de-Fonds, Switzerland. With the UltraFino Carbon, Bianchet doesn’t just rewrite the rules of tonneau watchmaking—it reinvents the form entirely.
