Astronomical clock - Glass, Copper, Wood - 1990-2000 - Astronomical desk clock

Astronomical table clock (also known as a tellurium) that not only tells the time but also simulates the movements of the Earth and the Moon. Modelled after the Millennium Clock by Franklin Mint in collaboration with the Royal Geographical Society. The movement is wound with a key and runs well. In the base there is a display that counted the years up to 2000 and could now show the date there. The battery is dead and we haven't been able to figure out how to replace it.
