Hermle's Astrolabium Mantel Clock
Hermle's Astrolabium beautifully finish in a solid wood base mahogany finish and a polished brass plate and crystal glass dome. The dial is round with roman numerals and features an exquisite laser cut center pattern. The highly accurate quartz regulated astrolabium has a month and zodiac disc and sun, moon and earth ball. Through the visible highly intricate gear train system the astrolabium clock reproduces the annual orbit of the earth along the sun, with the earth rotating around its own axis once in 24 hors and the moon revolves around the earth in 29-1/2 days, completing a full rotation around its axis. In the course of one year, the earth passes all twelve zodiac signs, months and individual days, which are indicated on the brass disc. Made in Germany. Dim: H 11-1/4" x Dia 8-1/4"
