Roger Dubuis Twofold

Playing with the highest standards of Haute Horlogerie, Roger Dubuis presents a new interpretation of its signature movement, the double flying tourbillon.

The Roger Dubuis Excalibur Twofold is a high-tech mechanical timepiece that represents three world premieres.

Roger Dubuis Twofold

Firstly, the exterior parts of this 45mm watch (Case, bezel, crown and case back) are 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.

The second world premiere feature of this timepiece is the unique luminescent display of the movement. For the first time, a patented process was developed to light up every angle of the upper plate of the movement composed of MCF. This special luminescent coating used for this double tourbillon movement lasts 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.
