Signed, Sharon - Temple Middle School. From the moment we're born, to the moment we die, most people are preoccupied with time. Watches are really just miniature clocks. So to know about watches, you'll have to understand what a clock really is.
All clocks have two things in common.
First, a clock has a regular, repeating process that marks off moments of time. Second, a clock has a means of keeping track of these moments and displaying the results. The very first clocks used things from nature to measure time. Sundials tracked the passage of the sun across the sky. Water clocks measured the flow of water through channels and tubes.
