The Tempus Watch is a magical wristwatch that is able to stop time. It was named after the ancient word for time as it was originally found in Italy.
The watch has two studs. One stud, or plunger as it is sometimes called, is able to stop time for up to two hours, requiring five minutes between each use. The second stud allows the wearer to freeze whoever or whatever they think about when pressing it for up to two hours, and unlike stopping all of time it has no limit in between each use. Additionally anything individually frozen can be 're-frozen' while the first duration hasn't been completed, just requiring the user to do it within the two hour limit.
