Thousand-year moon phase mechanism
What will first and foremost fascinate the clock enthusiast is the precision with which the Lange designers have calculated the transmission of the moon phase indication for exactly 1000 years to come - the engineers did not settle for the conventional moon phase calculation which assumes that the moon travels around the earth in approximately 29 days, but tried to adapt to the actual astronomical conditions; these are based on the exact time of the synodic month, which is 29 days, 12 hours, 44 minutes and 3 seconds. The "Big Dipper" with its seven similar sized stars is depicted with gold appliques. Next to the centrally located star "Mizar" is the smaller "Alcor" (Arabic: saddles), which in ancient times was used as a popular test object for excellent sharpness of vision.
This means that the “1815 MONDPHASE” follows the same principle of calculation as the very large astronomical clocks do.
