A watch is borrowed, the magician does not carry anything! After showing the watch to those nearby who notice the current time, you place the watch face down in the spectator’s hand. His hand is closed over the watch. The magician doesn't not touch the watch again. The magician then asks the spectator to name a number and then to concentrate on that number and the watch. He
opens his hand, turns over the watch and sees that the hands of the watch have moved that many minutes! This trick does not require any gimmicks.
