A watch is something you can use to tell the time on. Watches are small and usually have a strap on, so you can wear them around your wrist. Large watches that you hang on the wall are called clocks.
It is useful to know the time, so you know when to go to school, or have dinner, or watch your favorite TV show.
Brought is the past tense of bring. For example, "she brought some wine to the dinner party".
