Solar watch – Harness the power of the sun

Core features

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.

walnut wood

Elegant & durable. The distinctive grain and the diverse range of colors from chocolate brown to almost black brown make this type of wood one of our favorites for the production of watches, jewelry, sunglasses and handbags.
Walnut wood also impresses with its high density and the associated stability, which promises your piece of nature a long life!

Solar watch – Harness the power of the sun

A solar watch draws 100% of its power from the sun, the most powerful natural force of all. This means no more changing batteries – once charged, it simply stores solar or artificial light from wherever you are.
It takes just 5 hours of sunlight to charge. Only if you go without any light for 12 months straight will this reserve run out and the watch will stop.
Discover the charm, comfort and innovation of solar watches and let the sun power your time!
