My clock is based on the Astronomical Clock in Prague.
Outer ring -- This is an approximation of old Czech time and show the hours until sunset, with the golden number 24 marking the time of sunset.
Main ring -- This shows the hour according to astronomical time, with noon at 0 degrees. The golden hand points to the current hour.
Inner ring -- Shows the signs of the Zodiac and the position of the sun on the hand pointer is supposed to identify the current Zodiac sign.
