One of only 15 in the world. The Astrolabium is Hermle's astronomical table clock: beneath its glass dome the earth turns on its own axis every 24 hours while it travels its yearly orbit of the sun, and the moon circles the earth every 29.5 days, showing its phase as it goes. A brass disc carries the zodiac, the months, and the date. The movement is a precision quartz skeleton, visible in full through the dome, and the case is finished in rose gold. Made in Germany.

About Hermle
Franz Hermle & Sohn was founded in 1922 in Gosheim, in Germany's clockmaking heartland near the Black Forest. Within a decade it had become one of the most advanced makers of clock movements in Europe, and it remains among the world's largest manufacturers of mechanical movements. Now in its third generation, Hermle builds every movement in Germany and supplies clockmakers across the globe.
