Astronomical Clock

This beautiful piece is one of those long-term projects (like the 10,000 year clock) that we just love to follow. Clock expert Mark Frank's clock was featured in some clock magazines and blogs, and here is a great little YouTube video showing it off.


From Mark's Blog:
This is a four train, quarter striking movement with the fourth train driving the astronomical systems. The escapement is based on Harrison's H1 design and is driven by dual swinging-frame remontoire. The clock's functions include: 400 year perpetual calendar, equation of time, sidereal time, sun/moon rise and set, moon's phase and age, tides, solar/lunar eclipses, planisphere, tellurium, and full-featured orrery to Saturn with functional moons. There will be over 20 complications.
