Counterclockwise Watch

This watch, rather than marking the forward march of time (which is still marching on), makes time run backwards when it's wound. And instead of numbers around the dial, it just has twelve tiny pictures of monkeys on it. See? Twelve monkeys! See? Twelve monkeys!

When wound, it will allow you to undo any action - this means you can try again for a better roll, or take a different action. Can be used 5 times before it's mechanism breaks.
