What makes Holzkern special
Core Features

Ceramic
A timeless beauty. Ceramic is an exclusive material that has been used to craft high-quality timepieces since the 1980s. It is extremely robust, scratch-resistant, and provides a comfortable wearing experience. UV-resistant and waterproof, ceramic products retain their beautiful appearance for years. However, above all, we value the material for its infinite diversity of colors, which means that we can unleash our creativity and spoil our customers with new striking designs.

Minimalistic Everyday Style
Hydro-Defense Technology
Our HydroDef technology takes the resilience of natural materials to the next level. By means of a special resin coating, exposed elements of natural materials are significantly better protected from weather conditions (especially water).
Hydro-Def makes your piece of nature a faithful companion for all-purpose wear!
