Not exactly a magic trick- but you can turn it into one!
The previous owner actually used this watch case to produce a prediction.
We only have this one- so if you want it, better grab it!
This eyecatching pocket watch case is an accessory that makes a statement all on its own.
The case has an intricate hunter's pattern on the front and a floral pattern on the back.
The chain (included) will allow you to wear the watch case as part of your costume.
The top cover of the case opens, and there is space where the face and clockworks would have gone.
You can use this space to hold a written prediction, for example.
In the course of performing a trick, you can state that you have made a prediction, and then produce the watch case and open it to show the prediction.
That's just one way to use it as part of a trick, and that's the way the former owner used it.
