By using the iconic Golden Number 1.618 and the work of Italian mathematician Fibonacci as design basis, coupled with a minimalist essential approach to watchmaking construction, Bianchet creates a collection of modern and refined watches, in which beauty and harmony come to the fore. Limited Edition #3/10

Uniting the sensory, cultural, mathematical and mechanical, this skeleton tourbillon was designed according to the principles of the Golden Ration 1.618 and the Fibonacci sequence. Entirely made and finished by hand in Switzerland, the Tourbillon B1.618 Openwork is a true expression of conemporary Haute Horolgerie. The tonneau shape of the case, the design of its movement, the Italian aesthetic sensibility, the French sense of details; everything within it expresses refinement, pure lines and a natural sense of balance.
