The watch-car collaboration is a category with more misses than hits, but when the engineering philosophies genuinely align, the result can be more than the sum of its parts. Bianchet and Maserati have come together to unveil the UltraFino Maserati Flying Tourbillon ahead of Watches and Wonders 2026 in Geneva, where we will see it in person and report on the ground. This flying tourbillon is limited to 100 pieces and timed to mark the centenary of the iconic Trident emblem that first appeared on the Tipo 26 at the 1926 Targa Florio. This collaboration follows the failed collaboration between Audemars Piguet and Maserati two decades ago.
Things to Know About the Watch
The design vocabulary is rooted in the Maserait MCPURA's birdcage-design wheel architecture. The open-worked skeleton dial translates the car's triple split-spoke layout into a trident motif at the dial level — a structural reference rather than a decorative flourish.
The AI Aqua Rainbow finish, which debuted on the Maserati MCPURA at the 2025 Goodwood Festival of Speed as part of Maserati's Fuoriserie Collezione Futura program, carries through to the watch dial and accents the rubber seam running along the case edge, generating the same prismatic character on the wrist that it achieves on bodywork at speed.
The case itself is constructed in high-density carbon fiber with vulcanized rubber, keeping the total weight to just 36 grams without a strap, a figure that makes the 9.9 mm total thickness of the watch feel even more relevant. Grade 5 titanium bridges and main plate mirror the torsional rigidity of MCPURA's carbon-fiber chassis. The hand-finished crown is protected by integrated carbon crown-guards, both the bezel and case back are fitted with glare-proof sapphire crystal, and water resistance reaches 50 meters.
Two strap options are offered: an integrated high-density carbon fiber bracelet and a natural vulcanized rubber strap with a titanium folding clasp. The edition of 100 pieces is keyed to the Trident centenary, each individually numbered and produced at Bianchet's La Chaux-de-Fonds atelier.
The Movement
The Bianchet UT01 calibre drives the UltraFino Maserati: a hand-finished automatic flying tourbillon beating at 21,600 vph with a 60-hour power reserve. Every component of the movement is finished by hand: sand-blasted, satin-brushed, polished, and hand-beveled across the bridges, main plate, and tourbillon cage. The suspended mainspring barrel eliminates the traditional ratchet wheel to recover vertical space, enabling the movement to achieve a remarkable 3.85 mm thickness while maintaining that 60-hour reserve.
The tourbillon cage in Grade 5 titanium measures just 2.66 mm thin and houses a large screw balance wheel with variable inertia, preserving visual presence without compromising functional margins. In a nod to the MCPURA's suspension engineering, dedicated shock-absorbing solutions are integrated at both the balance wheel and structural levels, enabling the movement to withstand forces of 5,000 Gs. Total component count is 225 with 29 jewels.
On the Wrist & Price
The new Bianchet UltraFino Maserati is the kind of collaboration that earns its concept: two brands sharing Italian DNA—as Rodolfo Festa Bianchet has Italian roots—, a genuine shared commitment to lightweight materials, hand-finishing, and visible mechanical architecture. One hundred pieces is the right number for scarcity without being performatively so, and built to a standard that justifies the Bianchet name on the dial alongside Maserati’s Trident.
