The B1.618 UltraFino refines the concept of ultra-thin mechanical watchmaking, where precision engineering and structural efficiency converge in a timepiece designed for uninterrupted wear. Its construction prioritizes elegance and resilience, maintaining mechanical integrity within an exceptionally slim profile.

The flying tourbillon, paired with a golden rotor, enhances the movement’s efficiency while preserving a sense of depth and lightness. Every component is positioned with purpose, ensuring functionality remains uncompromised within the caliber’s refined architecture.

With shock resistance up to 5000G and water resistance of 5ATM. The 8.9mm-thick case, in high-density carbon offers strength without excess weight. Designed to be worn effortlessly, the B1.618 Flying Tourbillon UltraFino embodies technical sophistication and refined practicality.
