The Moon Clock - AstroMedia
This clock goes by the moon. Very precisely.
And like the moon, this astronomical clock also goes very slowly. It takes 29 days, 12 hours and 44 minutes for the moon to show all of its phases, exactly the average time from one new moon to the next.How is that possible?
In the moon clock, a half-white, half-black ball is rotated very slowly by a special clockwork so that it continuously shows the current phase of the moon from minute to minute, from the first delicate crescent moon to the waxing half moon to the full moon and then back to the new moon. The representation of the phases is as precise as the moon itself, because this large ball in space, which is always half illuminated, does the same when interacting with the sun.The moon clock from AstroMedia has historical models in the large astronomical clocks of the Middle Ages, but as a wall and table clock it is probably the first and only one in the world to show the changing phases of the moon in this way. Assembling this cardboard kit with a special clockwork is straightforward and quickly leads to a very elegant result.
