The Revolutionary Bianchet UltraFino Rotondo: A New Era in Watch Design
While a round case may seem like an ordinary concept in watchmaking, for Bianchet, it represents a groundbreaking shift. At Watches and Wonders 2026, the brand will unveil the UltraFino Rotondo. Although it shares some characteristics with the previously known UltraFino, this new model marks a significant departure from Bianchet’s signature tonneau case shape. For the first time, the brand is introducing a round case along with a round movement architecture, paving the way for something truly unique.
A Significant Shape Change
Since Bianchet first gained popularity, it has faced ongoing comparisons to other brands. I’ve addressed this issue before and believe it’s important to look beyond surface-level observations. Many critics hastily conclude that the tonneau case and skeletonized movement merely mimic established designs. This notion feels a bit simplistic and perhaps a bit unfair.
I never completely bought into that argument. Sure, both watchmakers and styles may overlap, but Bianchet’s intent and execution have always felt distinct. The UltraFino, in my view, represents something deeper within horology—an embodiment of traditional craftsmanship presented in a contemporary format.
With the introduction of the Rotondo, Bianchet is stepping away from the tonneau form. What remains is the essence that always mattered most. The watch retains its skeletonized architecture, flying tourbillon, commitment to lightweight engineering, and performance-driven design—all framed within a round case that better encapsulates the brand’s identity. If anyone still wishes to dismiss Bianchet as an imitator after this, I wonder what more the brand could do to prove itself? Critics will always find something to critique, I suppose.
The Movement – The Heart of Innovation
However, the true marvel lies beneath the surface. At the core of the UltraFino Rotondo is Bianchet’s own caliber UR01, an ultra-thin, automatic flying tourbillon movement measuring just 3.85mm in thickness. This alone is noteworthy. When you factor in a 60-hour power reserve, a suspended barrel, a screw balance wheel, a solid 18K rose gold rotor, and an impressive shock resistance of 5,000 g, the movement’s significance really comes to life.
What truly sets Bianchet apart is its emphasis on both design and performance. Crafting an ultra-thin automatic tourbillon is one feat; crafting one that is lightweight and rugged enough for everyday wear? That’s innovative. A movement under 4mm thick that also boasts resilience capabilities is something that deserves more recognition.
Additionally, Bianchet goes beyond simply housing an appealing movement. Each caliber is developed and produced in-house, meticulously finished in their La Chaux-de-Fonds workshop. From Grade 5 titanium bridges to hand-beveled components that take over 30 hours to complete, this is not just a surface-level approach to watchmaking. It’s a testimony to true craftsmanship.
Designed for Real-Life Wear: Slim and Lightweight
But it’s not just what’s under the hood. The UltraFino Rotondo sports a compact 39.5mm × 8.9mm case that combines the automatic flying tourbillon with a remarkable 100m water resistance. This is sure to attract those who appreciated the technical ambition of earlier UltraFino models but found themselves less drawn to the tonneau shape.
At launch, there will be two versions: one in Grade 5 titanium and the other in forged carbon fiber. Both models feature integrated bracelets and come with an additional rubber strap and titanium folding clasp. Weighing in at just 30 grams without the strap for the titanium version and only 26 grams for the carbon model, these are exceptionally lightweight watches. Even with the bracelet, you’ll carry only 75 grams for the titanium and merely 48 grams for the carbon—stunning figures for a watch of this caliber.
Visually striking, the Rotondo boasts a clean aesthetic devoid of excessive screws, and the architectural tension in the case and bracelet surfaces showcases Bianchet’s design philosophy beautifully. The skeletonized movement is on full display, allowing the elegance of the craftsmanship to shine.
Final Thoughts on the Bianchet UltraFino Rotondo
While I reserve full judgment until I can see the UltraFino Rotondo in person, I am excited about the prospect of comparing it directly to the Tonneau model. Bianchet’s watches are known for their in-person allure, and I expect this one will be no exception. At this stage, it feels like one of the most significant launches the brand has made. It’s not merely about the round case; it’s about reframing the brand’s narrative in a way that resonates more profoundly. The Rotondo encapsulates the ambitious, technically impressive craftsmanship that Bianchet is known for, in a form that makes the artistry unmistakable.
The Bianchet UltraFino Rotondo will be available at CHF 62,500 for the titanium model and CHF 67,500 for the carbon variant, excluding taxes. I’d love to hear your thoughts on this new release in the comments below.
