The Chronogeoscope is an educational software that makes it possible to study the conceptual tie between time and place in a watch.
The idea: Your location on a map of the Earth provides the hour hand of a 24 hour clock. By reading the number on the hour ring corresponding to your location, you know what the solar time of your location is. So you are not actually using a clock, but a model of the Earth's rotation, in order to get an idea of the current time.
