Due to the manual techniques and traditional methods used to manufacture and finish our components, each of our pieces has its own unique fingerprint. Although unified in their exceptional precision, no two pieces are identical, thus is the nature and romance of artisanal horology. If you would like to view the making of, photos and videos are posted regularly on our social media – see the links below.
We make and finish our German silver mainplates and bridges in our atelier, piece by piece. They are non-plated to retain the warmth and authenticity of the material and will age accordingly.
Our movements feature traditional hand finishing and decorative techniques such as black-polishing, anglage, grainage, satining, perlage and colimaçonnage.
“ELITE WATCHMAKING MAY BE INDEPENDENT BUT IT IS ALWAYS A COLLABORATION.”
Since its beginnings more than four centuries ago, watchmaking in Switzerland has always been a collective unification of savoir-faire. The inherent value being in the expression of innovation and precision achieved and not by who’s hand it arrived.
The true measure of fine watchmaking is not defined by who made every individual component, but by the quality of the finished whole. At its highest level, excellence emerges through the combined knowledge of diverse métiers, each contributing generations of experience to a common purpose and not a personal statement of acheivement.
Our workshop is no exception. While we manufacture the majority of the movement components ourselves, we proudly entrust certain specialised parts to a small number of exceptional partners. We see this not as a compromise, but as a continuation of the collaborative spirit upon which our industry was built.
