What Is a Deployment Clasp on a Watch?

A deployment clasp is a closing mechanism on a watch that allows the band to be fitted to the wrist. It allows for the band to be made tighter.

The deployment clasp is an invisible clasp with 2 sides that fold over providing a more secure fit. It generally allows for the watch to look better than the loose clasps that hang off the wrist. Invented by Cartier, it is one of the more stylish options when it comes to watch closures. Deployment buckles are not as easy to use as most. They must be positioned a certain way, in order for them to work correctly.
