I have a good friend. It has a round face. On its face, it has three hands. One is short, the other two are long. It has no arms, but its hands turn round and round. It has no feet or legs, but it can go all day and all night.
It has no eyes and no ears. It has no mouth, but it can talk. In the morning it can wake me up and tell me, "it's time to get up."
What is it?
