Core features

Automatic movement

Automatic watches use your movement to power them and therefore do not require batteries or battery changes. Whether with a small viewing window or great skeletonized details, you can see your movement in action. But don't worry, with a power reserve of at least 35 hours, your watches will keep running even if you take a break.

marble

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 coloring, marble provides a particularly aesthetic appearance that makes our watches and jewelry made from this stone very special statement pieces.

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.
