The tongue or tang, a part of a tang buckle mechanism, is an important component. It essentially refers to the metal prong that fits into the holes in the strap, thus locking the strap at the desired size. This way, it ensures a secure fit while being very easy to use and adjust. With its muscular and simple design, the tongue is an essential piece of traditional watch strap buckles that works with reassuring reliability but also functionality. This diminutive yet worthwhile element is precisely molded to avoid harming the strap without losing anything in its snug fit that holds the timepiece securely on the wrist.
