Bianchet Tourbillon B 1.618 Openwork

Bianchet is a Neuchâtel based luxury Swiss watch brand co-founded by Rodolfo & Emmanuelle F. Bianchet. The brand creates fine mechanical timepieces entirely made in Switzerland.

Bianchet’s debut timepiece, the Tourbillon B 1.618 Openwork is a high-horology creation imbued with both practicability and sportiness. Meticulously combining beauty, strength and elegance, this micro-mechanical marvel reflects the brand’s immense expertise in luxury watch making and excellent vision.

This timepiece is a result of three years of work. It is then finally fine-tuned by a creative team who combined the Italian and French sense of style with the Swiss horological know-how and attention to details.

Bianchet Tourbillon B 1.618 Openwork

Bianchet Tourbillon B 1.618 Openwork takes its inspiration from Fibonacci’s golden ratio 1.618, which has been widely used in the arts, architecture and music.

The Bianchet Tourbillon B 1.618 Openwork watch features a well-designed tonneau (barrel shaped) case made from titanium. Its intricate mechanical movement is revealed through sculptural titanium plates and bridges, providing ultimate transparency. The three-dimensional design is composed of interlacing arches and circles, based on Fibonacci’s golden proportions, which convey a deep sense of harmony.

The movement plates and bridges, the titanium tourbillon cage, as well as the watch case, are crafted and manufactured by Bianchet, in the heart of the Swiss Jura Mountains. Every Bianchet watch is entirely made and hand-finished in Switzerland.

Sophisticated milling and finishing processes as well as a high level of craftsmanship skills are necessary to shape the intertwined openwork plates and bridges, made from a highly inflammable titanium alloy. The complication of the movement comes from the superposition of structural and aesthetic elements conceived to create ethereal and strong openwork architecture.

Made from Titanium, the Tourbillon B 1.618 Openwork is lightweight yet robust timepiece. Thanks to its impressive water resistance of 50 meters and shock resistance up to 6000G, this contemporary mechanical watch can be worn for sports activities also. The watch also provides 110 hours of power reserve.

The slightly curved 54-gram tonneau case features a complex ergonomic construction, which is underlined by two thin lines of soft vulcanised rubber.
