Antique Clock

An incredible prediction.
You show the spectator your new clock on your device. It is a beautiful antique clock. You show how you can set the hands of the clock. Then you turn away and set the hands to a certain time: your prediction. You ask the spectator to think of a time, any time he wants. You dont touch any buttons, controls or the screen after that.
When he tells you the time he thought of, you show him the time that you set on the clock: it is exactly the spectators thought of time.
