Mechanical watch

A mechanical watch is a device that helps you keep track of time just like a clock or a phone. But it's not powered by electricity like those devices, instead it uses mechanical parts like gears and springs to keep ticking and keep the time moving. So when you see the little hands on the watch face moving, it's because these gears are moving them.

Think about it like a toy car that you have to wind up by turning a little key, and then it runs. That's how a mechanical watch works too. The watch has something called a "mainspring," which is a little coiled-up spring, and you have to wind it up to make sure the watch keeps running. When you wind the watch, the mainspring gets tighter, storing energy that the watch then uses to keep ticking and keep the time moving.

The watch also has something called an "escapement," which helps regulate the movement of the gears so that they move at a precise rate. This is what helps the watch tell you the exact time. When the escapement is working correctly, the gears move a certain number of times per second, and this is what moves the watch hands.

All of these little parts work together to keep the watch moving accurately and track the passage of time. And because it doesn't rely on electricity, a mechanical watch can keep going for a very long time as long as it gets wound up regularly.
