What is the term used for a watch where the movement is exposed for viewing?

The term that refers to a watch where the movement is exposed for viewing is a skeleton watch. This type of watch is designed to showcase the intricate mechanics of the movement, often through cutouts in the dial or a transparent case back. By removing parts of the dial and other components, the craftsmanship and engineering of the movement are highlighted, allowing enthusiasts to appreciate the horological artistry and the functioning of the watch from the outside.

This aesthetic appeal is not just about beauty; it also reflects a level of sophistication in watchmaking, where every gear and spring can be seen at work. The design philosophy of skeleton watches emphasizes transparency and the elegance of the inner mechanics, making them a popular choice among collectors and watch aficionados.
