"Carlo Heller's sundial is a precision instrument, sensational, aesthetically pleasing, weather-proof and handcrafted in an unusually loving fashion: It brings a totally new perspective to the ancient idea of time measurement via the earth's orbit of the sun."

The Frankfurter Allgemeine Zeitung (FAZ) writes about the HELIOS Subsolaris and its inventor on 4 September 2001. Until today Helios e.K. offers you an exclusive range of accurate sundials with modern design.

In order to offer our customers the widest possible variety of sundials, we have included special products from other manufacturers in our range. These include the historic ring sundial by Michael Kala, whose sons Hannes (pictured) and Matthäus have taken over the reins of the manufactory. We would also like to recommend the glass SOLEMIO cylinder sundial by Dr. E. Kretschmann and the Naseweis sundial for little adventurers from the Ostalb workshops, a recognised workshop for disabled people.

Piet Hein (1905-1996) - multi-thinker and universalist. He brings poetry, geometry and design together in a harmonious design, where function and art is weighted equally.
