The art of patina: how copper tells stories
craftmaterials
Copper is a living material. From the moment it leaves my workshop, it starts breathing — oxidizing, changing, telling the story of its owner.
Why copper?
In a world of plastic and cheap alloys, copper is resistance. It is a material that demands respect and returns character. My copper watches are not just timepieces — they are living artifacts.
The patination process
In my workshop, I hand-patinate each case using a process I’ve been developing for over three years. The result is a unique pattern that continues on the owner’s wrist.
Steps
- Cleaning — Thoroughly clean copper of organic impurities
- Etching — Controlled etching creates texture
- Patination — A mixture of acetic acid and salt
- Fixing — Protective layer preserves the desired tone
- Aging — Natural aging continues the story
