How Does a Watch Keep Time Without Electricity?

A mechanical watch keeps time using tiny gears and springs inside it. When you wind the watch, you're like giving it a big hug, it stores energy that makes the hands move. It’s like when you stretch a rubber band and let it go; it snaps back to its original shape. The spring in the watch works the same way, keeping it ticking for hours or even days.
