26th February, 2025: Bianchet has redefined the tonneau-shaped sports watch with the introduction of the B 1.618 UltraFino, a timepiece that seamlessly blends ultra-thin haute horlogerie with everyday wearability. This groundbreaking watch features Bianchet's first automatic flying tourbillon movement, the UT01 caliber, crafted from titanium and designed around the Golden Ratio (1.618), embodying a perfect balance of sophistication and technical prowess.

Where Ergonomics Meet Haute Horlogerie
The UltraFino stands out for its exceptional comfort and resilience. Despite its sleek, curved tonneau case, measuring a mere 8.9mm in height and 40mm in width, it can withstand shocks of up to 5,000Gs and water pressure of 5 ATM. This remarkable combination of elegance and robustness makes it an ideal everyday companion.
Two Expressions of Timeless Design
The UltraFino is available in two distinct versions: a skeleton model showcasing the intricate UT01 movement and a dial version featuring the exclusive Golden Diamond pattern, a contemporary reinterpretation of the Clou de Paris motif. Both versions highlight Bianchet's signature rubber seam between the bezel and case middle, underscoring the brand's commitment to craftsmanship.
The UltraFino Skeleton reveals the ultra-thin UT01 movement, an engineering marvel just 3.85mm thick and weighing 8 grams. This titanium movement, paired with a gold rotor designed with Fibonacci spirals, showcases Bianchet's dedication to mathematical beauty in design.
A Rare Feet in Watchmaking
Bianchet has pioneered the integration of a metallic bracelet with a tonneau-shaped case, a rare feat in watchmaking. The UltraFino's fully integrated titanium bracelet enhances the watch's fluidity and ergonomics, creating an unbroken line of sculptural elegance. A vulcanized natural rubber strap with a titanium deploying buckle offers an alternative styling option.
An Homage to the Golden Ratio
True to Bianchet's signature style, the UltraFino's design pays homage to the Golden Ratio. This mathematical principle, evident in the rotor's Fibonacci spirals and the case's contours, brings balance and harmony to the timepiece. The movement's rear bridges further exemplify this mathematical harmony, with proportions aligning with the 1.618 ratio.
The UT01 Movement
At the heart of the UltraFino lies the Bianchet UT01, an ultra-thin and ultra-light automatic tourbillon caliber crafted from titanium and gold. This movement, measuring just 3.85mm in height and weighing 8 grams, embodies Bianchet's pursuit of technical excellence and artistic precision.
The UT01 movement features a unique design approach that ensures outstanding efficiency, shock resistance, and chronometric precision. Its construction, guided by the Golden Ratio, showcases meticulous craftsmanship and attention to detail, from the hand-polished bevels to the circular satin-brushed wheels.
