The watchmaker Roger Dubuis is well-known for its unconventional, ingenious creations. Now, the new Roger Dubuis Excalibur Twofold is furthering the horology house’s reputation. The 45mm skeletonised timepiece displays a unique ‘ultra-white’ design and a double flying tourbillon. The case is made out of a mineral composite fibre and is presented on a matching white strap created with FKM luminescent rubber – a feature never seen before in the watch industry.
The novel use of a patented technique for the application of the watch’s glow ensures that each part of the movement’s upper plate keeps glowing green, lasting 60% longer than standard luminescent material commonly used. The hands, screw-like indices and Two-Fold strap also light up in the dark. Furthermore, the movement can be viewed though the watch’s caseback.
The Excalibur Twofold is powered by the horology house’s manual-winding calibre RD01SQ, with the mainspring barrel offering a 50-hour power reserve. The double-flying tourbillon offer a frequency of 3Hz each and provide high precision thanks to the differential system serving to average out the rate of the two tourbillon.
The Roger Dubuis Excalibur Twofold has been certified with the Poinçon de Genève. It is water-resistant to 30m and is limited to eight pieces at a price of 276,500 euros.
