Each Watch Winder is equipped with a crystal stone and thus is absolutely unique in the world. We put single stone hearts perfectly together to a breathtaking and precious mosaic. Agate comes from the Greek achates which is the old name of a Sicilian river, rich in precious stones of variegated colors. It evokes shades of the sea and maternal warmth and protection. When backlit, this particular quality of quartz creates delicate effects of the light.
