Core features

A dial made of marble

Our marble is formed in the depths of the Earth's crust. Minerals penetrate the rock, etching fine lines, forming wild patterns and giving every piece of stone its unique signature. Marble lives on in our watches - as an elegant dial that makes each piece unique. Every watch is a one-of-a-kind work of art – created for people who are looking for true individuality.

Tungsten

Tungsten, better known as tungsten carbide, is created by combining tungsten and carbon. Its exceptional hardness resists scratches and keeps it looking flawless even with daily wear — perfect for your everyday style! Its robust nature is ideal for an active life and gives your look a powerful, dynamic touch.

Weather-Resistant Design

Let your piece of nature be your companion in any weather.

For our weather-resistant designs, we carefully select materials to naturally withstand all kinds of weather. Whether it's stone, nacre or stainless steel, get your piece of nature and wash your hands without worry, or enjoy your next walk in the rain.
