Since 1995 Roger Dubuis manufacture is defined by “no limit” innovation, technical prowess, demanding savoir-faire, and stylistic audacity. Vivid proof of its excess in excellence, exclusivity, know-how, and performance, most Roger Dubuis watches bear the Poinçon de Genève —Geneva Seal. The use of avant-garde materials inspired by other cutting-edge industries —such as Additive Manufacturing and Composite Material technologies— highlights even further the expressive singularity of the Maison.
No limits in the design, no boundaries in the technical prowess. Just excess and beyond with Roger Dubuis. Playing with the highest standards of Haute Horlogerie, Roger Dubuis presents a new interpretation of its signature movement, the double flying tourbillon. The Excalibur Twofold is a perfect illustration of its expressive singularity and know-how that is even more striking in the dark.
This incredible horological creation represents three world premieres. With a 45mm case, the glacial touch of Excalibur Twofold is enhanced by the bezel and the case created in Mineral Composite Fiber —MCF—, an ultra-white composite material made of 99.95% silica and, specifically developed by Roger Dubuis. The Sheet Molding Compound —SMC— process mastered by Roger Dubuis engineers enables the Manufacture to play with this unique Mineral Composite Fiber.
For the first time, a patented process was developed to light up every angle of the upper plate of the movement composed of MCF. Luminescent at night and lasting 60% longer than standard luminescent material commonly used. Lastly, the Twofold strap is made from a specific FKM rubber and is also luminescent, based on a world-first technology named “LumiSuperBiwiNova” that makes part of the strap luminescent glow in the dark like a nocturnal signature.
The Roger Dubuis Excalibur Twofold is powered by the manual wound calibre RD01SQ with a double-flying tourbillon. The 301-part movement with 28 jewels features circular-grained and NAC coated plates and bridges. The movement provides a power reserve of 50 hours while beating at a frequency of 21,600 vph. Bearing the Poinçon de Genève, the Excalibur Twofold is available in a limited edition of only 8 pieces.
