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.
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.
