Wow! Wonderful!I have a French mantel clock with a Brocot perpetual calendar. There is a wheel in the calendar mechanism that rotates once every four years to manage the leap years.
Do the day and month pointers click to thext day and month?
Would love to see that
Depressing. None will geto see it move.btw if You look for slow revolving gears look at the astronomic clock in Straßburg/France : it contains a wheel turnin once in about 25700 years to demonstrate the so called Platonic year , the circle of the precession of the eath´s axis. That´s what I call slow turning!
