The highly accurate quartz regulated Astrolabium features a calendar and zodiac disc and individual representations of the  sun, moon and Earth. Through the visible highly intricate gear train system, the Astrolabium clock reproduces the annual orbit of the earth around the sun, with the earth rotating around its own axis once in 24 hours and the moon revolves around the earth in 29.5 days, completing a full rotation around its axis. In the course of one year, the earth passes all twelve zodiac signs, months and individual days, which are indicated on the brass disc.
