Astrolabium 22836-072987 – Hermle

Description

Astrolabium 22836-072987

The quartz-controlled Hermle skeleton movement with astronomical indications has a mahogany Astrolabium 22836-072987 at the top to complement the hour and minute display. The sun, moon and earth are moved by the movement via the gear train visible at the top in their daily, monthly (moon around the earth) and annual (earth around the sun) rotations in true-to-life time.

The date and month position are shown as signs of the zodiac in the upper display level on a decorative picture scale on the horizontal clock plate. The clock shows the Earth’s orbit around the sun once within a year. The earth revolves around itself once every 24 hours. At the same time, the moon orbits the earth once every 29 1/2 days, turning once on its own axis, so that the individual phases of the moon can be seen from the earth. The earth passes through the 12 signs of the zodiac, months and days, which can be read on a flat, cylindrical dial. The time sequences are shown identically, but not the geometric dimensions.

Movement: Hermle Quartz skeleton movement 2987, display month/date, zodiac signs etc., running time with an alkaline manganese battery, 1 year, baby cell type.
Glass bell: The crystal glass bell is mouth-blown according to an old, handcrafted tradition.
Small irregularities and defects are unavoidable with this handcrafted production method and are therefore characteristic.
