Accurate enough to count time.
A chrono watch is a watch that can also act as a stopwatch. The Chrno watch has a normal watch face, however the second hand on the watch can be stopped and started just like stop watch.
I suppose if your stop watch doesn't accurately measure time or has limit on the length of time it can measure it might be bad. Otherwise it would be an accurate measurement of the length of a movie.
stop watch

seed stop
I think the answer is Timer and stop watch
who invented the stop watch and who invented the themomitor

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.
Maybe
the size of a normal watch.
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.
