Timepieces with Solar-Tec movements use a source of energy that should be applied to as many of life’s situations as possible: the power of the sun.
Choose a model with Solar-Tec and forget about the problem of a battery change that comes with Quartz watches or the need to wind up automatic models.
With highly efficient solar panels and a battery runtime of 6 months or more, your watch with Solar-Tec will never let you down.

What glimmers so beautifully? Nacre comes from the shell of shellfish and is known for its extraordinary iridescence. When it comes to elegance, hardly any other material comes as close to beauty as this from the sea. In order to offer the perfect design for every personality, we use special dyeing techniques for nacre that make it shine in all colors of the rainbow.

You can always rely on our timepieces with luminescent hands and marks!
Special pigments absorb UV and artificial light and make the dial glow. This way, your piece of nature is not only a great companion to you during the day, but also during nighttime, helping you always get the time right, even in the dark.
The more time you spend in the sun, the brighter your watch will shine at night!

Thanks to our special constructions made from natural materials, your Holzkern model means you’re wearing a genuine piece of nature.
Enjoy the distinctive optic and feeling of wood, stone and other natural materials, and be inspired by their wearing comfort!
