How many hands on the first clock with hands???
Well since you said the clock had “hands” it must be at least two. And the first clock with at least two hands may have had more than two hands, but it must have had two before the others were added, and it would still have been a clock at that time. Therefore the first clock with hands had two hands!
I suppose one, because it was the most simple to make. 1) Sundial clocks had only one shadow hand, but I don’t know if you would accept this as a hand. Candle clocks and hourglasses have no hands at all. 2) The first water clocks did not have hands either: “In Babylon, water clocks were of the outflow type and were cylindrical in shape. Use of the water clock as an aid to astronomical calculations dates back to the Old Babylonian period (c. 2000 BC–c. 1600 BC).” “These clocks were unique, as they did not have an indicator such as hands (as are typically used today) or grooved notches (as were used in Egypt). Instead, these clocks measured time “by the weight of water flowing from” it.” The first indicators on water clocks were not hands rotating on a clock face, but rather translating pointers: “In China, as well as throughout eastern Asia, water clocks were very important in the study of astronomy and astrology. The oldest reference dates the use of the water-clock in China to the 6th
