Sonne & Zeit - Sonnenuhrenbau Heierli

A New Star in Sundial Heaven

About us

In 1999 I built my first sundial following classical specifications. Soon I began to design models according to my own ideas. From the first hour on I was inspired by the idea of ​​renewing the sundial and bringing it from outside to inside.

In 2017 my wife and I set up a small workshop to fabricate our products for sale.

We give our sundials a fresh, modern touch to fit the present taste. Our products are designed to be used both as a reliable timepiece and as an eye-catcher to embellish the sill of a sunny window.


Even in the age of atomic clocks, sundials earn their place in our lives.

They tell the time simply by observation of nature. They show the modern measures like coordinated time and forgone measures like the hour angle of the Sun. Set up precisely, they can point the direction of south just as well as a magnetic compass, and sometimes better.

Last but not least, sundials give us the time without supply of any form of energy other than sunlight.


We recently introduced our new model Terra for committed sundial enthusiasts - look at it
