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. A never-yet seen prowess in the world of Haute Horlogerie. 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. Combining lightness and resistance, this new technical masterpiece demands an extreme watchmaking savoir-faire. Bearing the Poinçon de Genève, the Excalibur Twofold is a limited edition of eight pieces.
