ETHEREAL SKELETON TOURBILLON A marriage of art, mathematics, and craftsmanship Born from a passion for beauty, the Bianchet Tourbillon B 1.618 Openwork watch for men is the result of three years of work and development by a creative team combining Italian, French, and Swiss talents. The very first model from the Bianchet house reflects its vision of Haute Horlogerie and its desire to embody beauty, strength, and elegance. A design inspired by the mathematics of harmony The architecture of Bianchet's first skeleton tourbillon caliber, the B 1.618, is inspired by the work of Italian mathematician Fibonacci on the golden ratio 1.618, which played an important role.
