Bianchet Tourbillon B1.618

Titanium-Carbon Limited Editions

Revealed during Geneva Watch Week at Barton7, Bianchet unveils two new limited editions of the Tourbillon B1.618 Openwork, which unite noble materials with a sporty and technological soul, and reflect the Franco-Italian brand’s statement to define a new essence of style in contemporary watchmaking.

Timeless design principles

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. 

Known as “The Divine Proportion,” the Golden Number 1.618, which underlies the beauty of the universe, is found in some of the most harmonious and everlasting creations in art, architecture, music – from Leonardo da Vinci, Le Corbusier, to Debussy – and in nature.

Fascinated by the capacity of the Golden Number, and its timeless design principle, to create beauty and harmony, Bianchet founders have chosen to immortalise its proportions in their horological compositions to build an everlasting legacy.

Italian by design, French in the details 

Created by the Franco-Italian couple Rodolfo and Emmanuelle Festa Bianchet, the brand lays the foundation for its inspiration through its faith in the purity of lines, its passion for contemporary design and architecture, coupled with a pure, intuitive sensibility nourished by Italian roots, and an innate attention to details.

The flowing lines, the sense of colour, the engineering concept behind every Bianchet timepiece are a perfect illustration of the Italian design approach and eagerness to create an object of desire, that is beautiful from its conception to its aesthetic execution. 

The tonneau shape of the case, the openwork design of its movement, the high-end finishing, illustrate the combination of Italian aesthetic sensibility and French sense of detail. Everything within the Tourbillon B1.618 Titanium-Carbon watch expresses refinement, pure lines and a natural sense of balance that makes it a watch of our time for our time.

Crafted with soul

Every Bianchet watch is designed, crafted, produced, and finished by hand entirely in Switzerland, including the strap and buckle. Each person involved in the creation of a Bianchet timepiece, from the founders, designers and craftsmen, to carefully selected partners, put their heart and soul into their work to produce the best of Haute Horlogerie in Switzerland.

The process of making a Bianchet watch is focused as much on quality and aesthetic, as on technical excellence, the main objective being to obtain a perfect balance between form and function. The art of Haute Horlogerie, mainly executed by hand, requires complete undivided attention; a suspended moment in time when the passion of the creator transfers to the object and conveys the highest level of quality.

Conceived for an active lifestyle, the slightly curved carbon & titanium case offers perfect comfort. The union of hand-finished Grade 5 Titanium on the bezel and back, and a light carbon fiber composite with an added titanium powder, which Moiré effect creates unique patterns on every timepiece, is underlined by soft vulcanized rubber seams which bring a sensuous feel. The perfect curves, the lightness and softness sensations, the high-end materials, create a unique horological experience.

Titanium Caliber B1.618

The movement of the Tourbillon B1.618 Openwork is the result of genuine aesthetic research. Conceived from the outset as a skeletonized movement, the Calibre B1.618 is all about a sensation of plumbing untold depths, a feeling accentuated by the curves, whose radii’s progression and interlacing are derived from the Fibonacci sequence. The symmetrical plays off the asymmetrical, in a balance that is natural to the eye, with a harmony that is intrinsic to the Golden Ratio.

Crafted from grade 5 titanium, that only master watchmakers are able to harness, the calibre B1.618 is able to withstand shocks of up to 6000G in all positions. The superposition of titanium arches and curves, in various shades of black, the floating skeletonized flanges which adorn the movement, play with light and transparency to create a sculptural architecture that is both strong and ethereal.


The tourbillon cage, the main plate and bridges, are all crafted from titanium and finished by hand, using mineral sands and natural fibres. Every wheel of the B1.618 gear-train is decorated by hand and coated with rhodium – today the most prestigious and expensive metal on earth.

Contemporary Haute Horlogerie

Thanks to peerless Haute Horlogerie techniques and the use of noble materials, featuring a sporty and technological soul, Bianchet timepiece collection reinterprets mechanical art in contemporary high-horology.

Uniting the sensory, cultural, mathematical, and mechanical, the new Tourbillon B1.618 Openwork Titanium-Carbon limited editions feature a hand-finished case in Grade 5 Titanium on the bezel and back, mixed with a light carbon fiber composite infused with a titanium powder, stylishly signed with two soft colorful rubber seams.

1.618 by Bianchet

Focused on re-engineering a timepiece by applying the Golden Ratio to contemporary watchmaking, Bianchet breaks free from the classical and traditional culture with which the iconic number 1.618 has generally been associated, and applies the Golden Ratio to a modern conception, using the materials, manufacturing techniques and performances of today, in the respect of centuries of high horology know-how.

Limited to 21 pieces each, the new Tourbillon B1.618 Openwork titanium-carbon blue and green editions stand as a modern and timeless testament to beauty in watchmaking, and bring a sporty-chic Haute Horlogerie timepiece to refined watch lovers in search of a unique horological experience.
