Core Features

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!

Walnut wood

Walnut wood

Elegant & durable. The distinctive grain and the diverse range of colors from chocolate brown to almost black brown make this type of wood one of our favorites for the production of watches, jewelry, sunglasses and handbags. In addition, walnut wood impresses with its high density and the associated stability, which promises your piece of nature a long life! Our walnut wood comes mainly from North America and is 100% FSC certified.
