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.

We do not manufacture all of our components in-house. Certain components are sourced from highly specialised Swiss micro-suppliers, examples are jewels, escapement components, mainspring etc…
