An astronomical watch is a mechanical clock or watch, which, in addition to the time, indicates also astronomical matters such as moon phases, the sun position or the positions of the major planets. These types of watches were built since about the 14th century.

Astronomical clocks

Well-known astronomical watches can be found for example in Ulm, Tübingen, Prague, Strasbourg and Besancon as well as in many other Central European cities.
