In the UK television show CountDown, the clock appears to run clockwise from 12 o'clock down to six o'clock (see Youtube video). Although I have never seen how the clock hand returns to the 12 o'clock point. After a round the camera seems to focus on the presenters, and contestants, thus when the next round is played everything is reset.
- The hand completes the whole circumference of the clock, returning to the top
- It reverses direction to go back
- A technician pulls the hand from the face, and places it back to the top. (Least likely because of the disruption).
