How Does a Wristwatch Work?

Wrist watches are like a little motor that is encased on your wrist. You can bring it anywhere. The escapement regulates how fast the watch goes. A balance wheel and the hair spring are called an harmonic oscillator. Did you know that to oscillate is to swing back and forth? But to slop y kiss isn't that gross? How do you know if it's right? Likeh do you have nightmares about springs not being the right tension? No, no.
