Tang Buckle
	Like a leather belt buckle, this traditional clasp is found on many leather and other non-metal straps.
Deployment Buckle or Invisible Double Locking Clasp
	The Deployment Buckle or Invisible Double-Locking Clasp is also known as the Hidden Deployment Buckle or Butterfly Clasp, because, when closed, the clasp is essentially invisible and it opens symmetrically like a butterfly. This is perhaps one of the most common clasps available and most preferred by customers because the clasp is not a distraction from the watch itself. The clasp is opened by pulling the joined ends of the bracelet away from the wrist. These clasps also come on some of the leather and other non-metal strapped watches.
Deployment Buckle with Push Button
	The Deployment Buckle with Push-Button is essentially the same as the Deployment Buckle in looks and function except that its locking mechanism is released by two small buttons on each side of the bracelet. It is advantageous because the locking mechanism cannot be released by pressure on the bracelet, but only by pushing the buttons. This reduces the likelihood that the watch will release the without the wearer knowing it. These clasps also come on some of the leather and other non-metal strapped watches.
Fold Over Clasp
	The Fold Over Clasp collapses on itself and locks via a pressure tab. The clasp typically has several micro adjustment holes (as seen in the image) that can be used to adjust the bracelet size by non-jewelers. In time, the pressure tab often wears out and the clasp no longer stays closed. This has led to the following three different improvements on the Fold Over concept.
Fold Over Clasp with Push Button
	This is the second of three improvements on the Fold Over Clasp. The Fold Over Clasp with Push Button Clasp provides a secure lock on a post that can only be released by pushing the two buttons. This improvement is more secure than the Fold Over Safety Clasp.
Fold Over Clasp with Safety and Push Button or Double Locking Fold-Over Clasp
	This is the third of three improvements on the Fold Over Clasp. This clasp combines the flap of the safety clasp with a push button lock to provide the wearer the maximum security available for any Fold Over Clasp.
Jewelry Clasp
	A jewelry clasp is the simplest of all clasps. It is a latch that snaps closed around a bar. It is released by gently lifting the clasp and unsnapping it from the latch bar. This clasp is almost exclusively available on ladies dress watches.
