Unusual Clock Always Shows The Time That Has Been Requested

How many times do we look at the clock and wish it was a different time? Here is shown a magic trick that reverses the management of time.
A painted clock-face will display any chosen time that the spectators nominate.
Whether they choose 3:00 o'clock, 7:00 o'clock or any number between 1:00 and 12:00, the magician is able to show that time on the clock-face.
Every move is slow and deliberate, with no difficult movements required. The hand of the clock is painted on, and yet with every showing, the time is different.
