Bianchet presents UltraFino Rotondo

For Watches and Wonders 2026, Bianchet expands its collection with a new facet: the circle. In contrast to its previous models, which feature tonneau-shaped cases, the UltraFino Rotondo makes its debut in a round case.

A New Case Shape

Bianchet presents its Haute Horlogerie timepiece in two variations: one in Grade 5 titanium and the other in carbon. Both materials are prized for their lightness and exceptional durability. While the titanium version offers a distinctive sheen, the carbon model stands out with its unique, naturally varied grain. Despite their remarkably low weight — 48 grams in carbon and 75 grams in titanium — and a slim profile measuring just 8.9 millimeters in height, the cases are water-resistant to 100 meters and engineered to withstand shocks of up to 5,000 G. Both versions feature a diameter of 39.5 millimeters and are paired with an integrated bracelet, complemented by an additional rubber strap.

The Dial as a Stage for the Movement

The dial places the meticulously finished in-house calibre UR01 with automatic winding firmly in the spotlight. Measuring just 3.85 millimetres in height, this mechanical microcosm comprises a total of 225 components and 29 jewels. Its aesthetic and technical highlight is the flying tourbillon in titanium, which dispenses with an upper bridge and appears to float freely in space. Another visual focal point is the barrel, where a power reserve of 60 hours is stored. In addition, a specially developed winding and setting mechanism has been integrated to reduce friction, enhance efficiency, and improve tactile feedback. Shock-absorbing solutions protect sensitive components on multiple levels, lending the movement a level of robustness that is unusual for ultra-thin tourbillons.

Each movement is hand-finished in Bianchet’s atelier in La Chaux-de-Fonds. The anglage of the bridges alone requires more than thirty hours. Every edge is meticulously shaped and polished by hand until the metal captures the light in a way no machine can replicate. A striking chromatic contrast is provided by the partially skeletonized rotor in 18k rose gold, which is equally refined in its decoration.

The UltraFino Rotondo in titanium is priced at 62,500 Swiss francs (approximately $80,000). The carbon version is available from 67,500 Swiss francs, (approximately $86,000).
