PURE VISTUOSITY
The UltraFino Monaco defies convention with its 9.8 mm thin case. The case is crafted from white quartz-fiber composite, a high-performance material derived from ultra-pure silica fibers and natural quartz. Used in aerospace applications, this composite offers exceptional strength, scratch and shock resistance, and a 5 ATM water resistance. ​
​
Dressed in Monaco's iconic red and white, the watch captures the spirit of the Principality through a contemporary lens: light, resistant and uncompromisingly chic.
Its composite case, ultra-light titanium movement and flying tourbillon are designed for demanding environments, while its proportions follow the natural harmony of the Golden Ratio,

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 Monaco is fitted with a red 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 white natural vulcanized rubber offers versatility, bringing a fresh contrast with the red details of the case, and allowing for easy interchangeability.
