Skeleton see-through watches and pocket watches are usually expensive because of the type of movement they have. Creating an automatic mechanical skeleton watch costs more than one with quartz movement. What happens if your automatic watch stops? You can't wear your wristwatch forever.

Put simply, a skeleton watch is a type of watch where the inner workings are exposed. Watches can be skeletonised by reducing the mechanism until only the most essential parts are left. All non-essential metal is whittled down until gaps are left in the dial.

To understand how a skeleton watch works, envision it as a miniature mechanical wonderland. The mainspring stores energy, the balance wheel regulates time, and the escapement controls the release of power. As the gears interlock and tick in unison, they drive the hands around the dial.

A watch movement (also known as a "calibre") is the inner mechanism of a watch which powers its functions. It is typically composed of gears, springs, and other components that control the timing of its hands or display. The three main types of movements used in wristwatches are mechanical, automatic and quartz.
