PURE VISTUOSITY
The UltraFino Sapphire defies convention with its 9.8 mm thin case. The sapphire’s hardness and scratch resistance are complemented by a white rubber joint that ensures an exceptional 5 ATM water resistance, a rare feat for a sapphire watch. ​
Machining a curved tonneau case in sapphire is among the most demanding challenges in watchmaking. The crystal must be shaped with micron-level precision, and the 1.2 mm curvature adds complexity that makes reducing overall thickness exponentially harder.
Achieving a case under 10 mm in height required not only perfecting the sapphire machining process, but also creating an exceptionally slim movement, without compromising resilience and precision.
​
ULTRA-THIN
AUTOMATIC TOURBILLON
A true feat of mechanical engineering, Bianchet’s ultra-thin and ultra-light automatic flying tourbillon caliber UT01 - weighing 8 grams and measuring 3.85 mm in height - embodies Bianchet's philosophy of pure design and high performance.
​
Crafted from Grade 5 Titanium, with a rotor in massive gold, the UT01 movement can endure shocks of 5000 Gs. ​​
To reach this achievement, Bianchet created a suspended barrel, a redesigned escapement, and an optimized winding and time-setting system, reinforced by advanced shock protection that ensures both precision and resilience.
The UT01 bridges and gold rotor are designed according to the Golden Ratio and Fibonacci spirals, creating a unique architectural harmony that complements the movement’s technical mastery. Finished by hand, every movement requires more than 15 hours of traditional hand bevelling.
DOUBLE STRAP
The UltraFino Sapphire is fitted with a white natural vulcanized rubber strap, secured by a grade 5 titanium folding buckle.
Soft yet durable, the strap brings a tactile comfort that complements the ergonomic curvature of the case, making the watch a pleasure to wear throughout the day.
A second strap in black natural vulcanized rubber offers versatility, bringing a bolder contrast and allowing for seasonal interchangeability.
