This video shows the disassembly of one of the more complex modules in the machine, perhaps only surpassed by the third-order perpetual calendar. The videos are essential for those that may need to service these components in the next 50 or 100 years, depending upon how much usage the machine serves. For me, this module contains one of the more interesting designs ever used in horology, that of the Antide Janvier variable, slant-wheel differentials. I only know of three other clocks that have used this design in the past to correct for the equation of time or the various anomalies of the Moon's orbit. For a further discussion of this components see: my-time-machines.net/astro_11-16.htm .
