Description

This watch is also known as: 831-22, 821-22

One single movement of mechanical excellency plus a stroke of pure genius combine Ptolemy's geocentric universe with the Earth at its center, and Copernicus' heliocentric universe with the Sun at its centre. This allows the reading of the astronomical positions of the planets in relation to the Sun and the Earth. The moon rotates around the Earth. A perpetual calendar indicating the months and the sign of the zodiac completes one turn in 365.24 days at the exterior. Ref.
