Altamira

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.

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!
