"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.
