A watch tells you what time it is. A stop watch measures the duration of a specific event such as a person running a race; the watch doesn't just run all the time, you start it and stop it.
Yes, but it won't be worth much at all.
The way to work a stop watch is by pushing the red button to start and then pushing it again to stop and that is how you work a stop watch and also the way to test someone on how fast they do something.
