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.

A touch of luxury. The name "marble" comes from the Greek word "mármaros", which means "shining stone". The history of marble dates back to ancient Greek and Roman art, where marble was used for sculptures and architecture. With its distinctive texture and colouring, marble provides a particularly aesthetic appearance that makes our watches and jewellery made from this stone very special statement pieces.

We stand for diversity and unique designs that carry function and stylish aesthetics. That's why we developed our Forever-Unique Caseback: the movement is protected by a veneer of wood or stone, which you can study and admire on the back of your watch!
The unique grains and structures are additionally covered by a glass plate and protect your natural work of art from external influences - for a lifetime!

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!
