Presentation
A unique pocket watch is introduced where the numbers are backwards on the dial. The spectator is asked to mentally think of a time that was important to them in the past.  
 
Specator is then asked to pick up the watch and place it  face down in his palm and begin concentrating on his time. When he turns the watch  face up, he is amazed to see the hands running  "Back in Time."
 
The magician asks the spectator for his special time, and when he announces  it, the watch abruptly stops exactly at that time. The spectator has been holding  the watch the entire time.
