Roger Dubuis’ new watch, the Excalibur Twofold, features three world premieres

The latest member of the Roger Dubuis Excalibur family, the Excalibur Twofold is a modern vision clad entirely in white, with three world-firsts presented in the materials that go into the making of its unique appearance. On the inside is a familiar brand signature—the skeletonised double flying tourbilllon, which is the perfect centrepiece to the futuristic aesthetics on the outside. There’s more to the watch exterior than meets the eye—in the absence of light, it glows like no other watch in the dark by employing new luminescent coating technology in artistic lines across the top of the movement and the straps. It’s an experience to be enjoyed by the select few who will come to own this limited edition of just eight pieces.

White Out

The 45mm case and bezel is crafted out of Mineral Composite Fibre (MCF), an ultra-white composite material made of 99.95 per cent silica that is specifically developed by Roger Dubuis and used in haute horlogerie for the very first time. The upper plate of the movement is similarly made out of MCF, marking out the star-shaped bridge and double tourbillon with a white outline.

Dark Side

When the lights go out, the watch reveals the secret it hides. The luminescent coating on the upper movement plate glows in the dark, cloaking the star-shaped and circular outlines in an electric glow. It lasts 60 per cent longer than the typical luminescent material that is used on other premium watches—the second world’s premiere incorporated into the Excalibur Twofold. Even details such as the brand logo, Poinçon de Genève seal and “Swiss made” mark on the dial are given the same luminescent touch.

Material World

The white straps are made with a special FKM rubber and features the third world’s first innovation—a luminescent technology known as LumiSuperBiwiNova, which is applied on the straps in a grid-like pattern to give it a futuristic glow in the dark.

A Brand Signature

Powering this new creation is the calibre RD01SQ, a skeletonised double flying tourbillon, which boasts enhanced precision via a differential system that averages out the rate of the two tourbillons.


Time Well Spent

More than a third of the 1,200 hours taken to produce this modern creation is devoted to finessing it for the Poinçon de Genève certification awarded to timepieces manufactured in the Swiss capital and having achieved the highest decorative and finishing standards.
