Bianchet Introduces The B 1.618 UltraFino: An Emerging Icon in Tonneau Sport Watches.

With its seamless integration of form and function, the UltraFino redefines the tonneau-shaped sports watch, elevating it to unprecedented levels of elegance and performance. The heart of this timepiece beats with Bianchet’s first automatic flying tourbillon movement, the ultra-thin UT01 caliber, crafted from titanium and designed around the Golden Ratio (1.618).  

A sleek, curved tonneau case, measuring just 8.9 mm in height and 40 mm in width, has been designed to conform seamlessly to the wrist with a 1.2 mm curvature from lug to lug. This thoughtful design ensures exceptional comfort, creating an experience where the watch feels like an extension of the wearer. 

While ultra-thin watches often sacrifice robustness, the UltraFino defies convention. It withstands shocks of up to 5,000Gs and water pressure of 5 ATM, offering a rare combination of elegance and wearability. This fusion of strength and refinement makes it an ideal everyday timepiece, proving that Haute Horlogerie can be technically groundbreaking and wearable daily.
