Our Metal-Core technology has been especially developed in order to make our watch constructions with natural materials even more durable. With timepieces that have this special type of construction, the clockwork is encased in an airtight metal jacket that guarantees a waterproofness of up to 5ATM.
We thereby unify the best of two worlds: natural diversity of materials & the longevity of our designs.

Elegant & durable. The distinctive grain and the diverse range of colours from chocolate brown to almost black brown make this type of wood one of our favourites for the production of watches, jewellery, 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.

To protect our wood and stone materials from breakage and external pressures, we combine them with 316L stainless steel, also known as "surgical steel". The composition of iron, chromium, nickel and molybdenum makes it particularly robust and corrosion resistant.
The shiny surface provides a flawless look and can be easily coated with other colours. This is our secret ingredient that guarantees your unique piece nature has a long and exciting life!

Thanks to our special constructions made from natural materials, your Holzkern model means you’re wearing a genuine piece of nature.
Enjoy the distinctive optic and feeling of wood, stone and other natural materials, and be inspired by their wearing comfort!
