Turned towards trying to decipher the images on/ in the clock. I have come to hypothesize that the whole thing represents an astrological chart of some kind. I think the symbols on the outer ring may be numbers in some foreign text, but I do not know which one, if at all. The symbols on the inner 8 rings appear to be those of the signs of the zodiac in, again multiple cultural languages. If you take a look at the attached photo, you can clearly make out the symbols for Aries, Capricorn, and the two wavy lines of Aquarius. The others I cannot seem to ID in this character set, so may be way off base here. What say you?
My theory started because there are twelve divisions around the face, 12 numbers on a clock, 12 months in a year, 12 signs of the zodiac, etc...
