The Challenge of Materials: Rethinking Watchmaking
Traditional watchmaking has been built over centuries on the work of metals. Transitioning to composite, and more specifically to Carbonium®, is not simply about changing materials: it is a technological adaptation.
We had to undertake a complete redesign of the case to ensure not only the machinability of the components, but above all its durability over time.

By moving away from metal standards to adapt the design to the properties of carbon, we rose to the challenge of balancing mechanical performance with absolute fidelity to the watch’s design. That is where the true complexity lies: ensuring durability without ever compromising the signature Romain Gauthier aesthetic.
Our expertise: mastery of structure
Transforming an idea into a technical reality requires a sharp expertise in the organization of matter. Where classic methods would have required increasing thicknesses to ensure strength, our mastery of the fibrous structure allowed us to achieve a fully composite, waterproof, robust, and refined case.

This attention to detail is evident even in the fibers of the material, which precisely follow the curve of the horns. This result, made possible by our expertise in component molding, proves that technical innovation is the ideal way to enhance the original design.

Carbonium®: A Unique Aesthetic Signature
Beyond its technical performance, Carbonium® offers an unparalleled visual signature. Each piece features a random marbled pattern, making each case unique. This contrast between the "raw" side of carbon fiber and the high-end finish of the movement creates a fascinating visual tension.
