Roger Dubuis: Let there be light

Roger Dubuis is known to push the boundaries of traditional watchmaking, and with its latest release, the brand lives up to its reputation.

The New Excalibur Twofold is proof that the brand is deeply anchored in the Swiss tradition of watchmaking but does not shy away from innovation. With a case and bezel made from Mineral Composite Fiber (MCF), a material made of 99.95% silica, the Excalibur Twofold boasts an ultra-white color with a satin-like finish. It gives it a pretty unique appearance and a sleek look.

MCF is made by layering sheets of quartz and blending it with a white coloring agent as well as Sheet Molding Composite to create the shape of the case. The same material is used to outline the double tourbillon and the star bridge of the skeletonized movement.

This 45mm watchmaking heavyweight shows its true colors at night when it lights up thanks to a special Super-LumiNova lasting 60% longer. The real novelty on this model is the rubber strap on which Roger Dubuis applied LumiSuperBiwiNova™ a component allowing the strap to glow up at night.

The Excalibur Twofold will remain a distant dream for a lot of watch aficionados as the brand will only produce 8 pieces. One thing is certain though, Roger Dubuis is only discovering the potential of the MCF and will produce other stunning timepieces using it.
