Here is a very interesting watch produced in the mid-80s of the last century.
Watch shows the position of the planets in the solar system from 1901 to 2200. You can set any date in this period and the watch will show the position of the planets at that moment. The watch also shows the passage of Halley’s comet. An interesting toy from the space age period : )
There is also a version that is in a plastic case, but this one all steel versionis much more attractive and valuable. This is a watch for those who believe that the earth is round and that the sun is the center of the our solar system … : ) : ) : )
