German Astronomical Clock in Brass and Mahogany
The Hermle Astrolabium pairs brass detailing with a mahogany base in a piece that models the motion of the heavens. Beneath its curved glass dome the earth travels its yearly orbit of the sun while rotating on its own axis every 24 hours, and the moon circles the earth every 29.5 days. An engraved brass disc tracks the zodiac signs, the months and the days.
The movement is a high-precision quartz skeleton, fully visible through the dome so you watch its detail at work.

Frequently Asked Questions
What is an Astrolabium?
An astronomical table clock. Beneath the glass dome, the earth rotates on its axis every 24 hours and completes its orbit of the sun over a year, while the moon circles the earth every 29.5 days. An engraved brass disc carries the zodiac, the months and the days.
Is the movement mechanical or quartz?
A high-precision quartz skeleton movement, fully visible through the dome. It runs for a full year on a single alkaline cell — no winding required.
How does it differ from the rose gold version?
The movement, functions and size are identical. The difference is the finish: this one has a brass mechanism on a mahogany base in a warm, classic tone, while the other is finished in rose gold on a white base. The rose gold version is also a limited edition of 15 pieces worldwide, which accounts for its higher price.
How large is it?
28.5 cm high and 21 cm wide — substantial enough to command a desk or console, compact enough for a bookshelf.
Does it need servicing?
A quartz movement does not require the periodic oiling a mechanical one does. Replacing the battery each year and keeping the glass clean is enough.
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.
