El Duco's Reincarnation

You take the watch from your pocket. The watch has a chain. You open the watch case and display the watch face. Ask a spectator to set the time and close the case. Unlink the watch from the chain and put the chain back into your pocket. Introduce a beautiful drawer box made of wood. The spectator puts the watch into the box and closes the drawer. Say the magic word, and when you open the box, the watch has disappeared! The drawer is empty! Slowly, you take the chain from your pocket. Linked to the chain is the watch! Let the spectator open the case to verify the time he has set. It is correct! Includes instructions. Very good condition.
