Core Features

Easy-Switch Bezel

Making our watches even more unique? We make it possible with our Easy-Switch interchangeable bezel system. A specialized construction of the case and bezel allows the bezel to be removed, and replaced via a simple twist movement, with watches that have this function.
One watch - an endless amount of styles. Long live diversity!

Metal-Core Technology

Metal-Core Technology

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.
