This motion, powered only by the law of gravity, makes the Orloj distinctive in the world among astronomical clocks showing the phases associated with the Moon. The mechanism was created by a good unknown maker, probably within the mid-17th century. Unlike the original device, the construction of which was described in a statement from 1570, this mechanism produces much smaller deviation from your actual lunar stage of approximately one day in five years. On nine October 2010, the Orloj's 600th anniversary was recognized with a light present on the face from the clock tower.A significant stimulus to improving the accuracy plus reliability of clocks was the importance of precise time-keeping for navigation.
