Intriguing. Accomplished. Disruptive. Bearing all of the hallmarks of a work of art, Roger Dubuis is proud to unveil the Excalibur Monobalancier. Crafted from Mineral Composite Fibre (MCF) to enshrine this skeleton automatic monobalancier in a pure-white case, it embodies the House’s commitment to non-conformity, capturing the attention of all those dazzled by its clean whiteness. For those who choose to blaze their own trail, to show what happens when rules are reinvented and creativity is unleashed, it is a timepiece that proves the only limit for Hyper Horology is one’s own imagination.
A pure white masterpiece
Inspired by similar materials used in aerospace, MCF balances lightness with rigidity to enhance the 42mm timepiece into a new work of art, with a case, bezel and crown crafted from this pure-white, high-technology material.
Representing the House’s technical mastery and its desire to push boundaries, MCF is engineered from 99.95% silica and made via a Sheet Molding Compound (SMC) process that enables freedom of play, new possibilities, and the creation of intricate designs thanks to its sturdy structure 2.5 times lighter than ceramic and 13 per cent lighter than SMC carbon.
Constructed with peak wrist-wear comfort in mind while never forgetting the importance of standout aesthetics, Roger Dubuis specifically developed the material to remain stable and highly resistance to UV, artificial and natural light, while the addition of pigments deepens its whiteness. To maintain the all-white aesthetic, a white rubber strap is the perfect accompaniment to complete the look of this truly striking watch.
A signature skeleton
Capturing the two sides of the integrated Manufacture, the Excalibur Monobalancier infuses the tradition of horological craftsmanship with a daringly disruptive attitude. The skeleton automatic monobalancier is one of the proudest examples of this.
With a transparent view of its self-winding movement held directly on the inimitable Roger Dubuis star, the RD820SQ calibre features a skeleton microrotor reduced to its strict essence at 11 o’clock. Specifically developed to be as efficient as a full-size rotor, its construction ensures the watch winds perfectly to guarantee 60 hours of power reserve. Creating a rotor in such a small size and within the signature skeleton is an accomplishment mastered by few.
Sealed with the prestigious Poinçon de Genève, with every one of the components carefully finished by hand at the Manufacture in Geneva, this impressive feat of creative engineering is much like any masterpiece and therefore limited to 88 pieces only.

Ref. DBEX0949
Description
The Excalibur Automatic Skeleton features an MCF (mineral composite fiber) case. This new white material in watchmaking is light as a composite material (it is even 13% lighter than carbon) but is way more machinable than ceramic. The MCF used on the watch has been specifically developed so the resin it contains will remain stable and the whiteness of the material will remain intact (high resistance to UV light).
