Why do watches have jewelry in them?

Wheels in a watch are constantly rotating while a watch is running. Wheels rotate on their pivots, which are thin posts on both ends of the pinion. This constant rotation causes friction, which in turn causes mechanical wear. To reduce friction and wear, the pivots rotate in synthetic sapphire jewels. Sapphire is used because of it’s hardness; only diamond is harder.

Do you know the Gear Train?

gear train is a mechanical system formed by mounting gears on a frame so the teeth of the gears engage. Gear teeth are designed to ensure the pitch circles of engaging gears roll on each other without slipping, providing a smooth transmission of rotation from one gear to the next.

How do mechanical watches store energy?

Mechanical watches are powered by a coiled spring known as a mainspring. As this spring uncoils, the amount of time that the watch can run diminishes. This remaining amount of time is referred to as the power reserve, winding indication, or up/down indication. An indication turning through an angle or a linear indicator appears on the dial to display the power reserve, similar to a car’s fuel gauge.
