Pros and Cons of Deployant Clasps and Ardillon (Tang) Buckles

After going through the long and arduous process of choosing a watch, you may think that you’re nearly finished with your purchase. But don’t get too excited because you may have another decision ahead of you.

If you’re purchasing a watch with a leather strap, then you may be asked to choose between a deployant clasp and an ardillon buckle. If you’re looking for more information on the two options, then you’ve come to the right place. We’ve listed out the pros and cons of both the deployant clasp and the ardillon buckle.  

Deployant Clasps

Deployant Clasps

The deployant clasp is a folding metal buckle that is found most often on a metal bracelet. However, some brands attach a deployant clasp to a leather strap. You can easily snap the clasp shut to secure the watch to your wrist or expand the clasp to take it off. 


1. More secure. If your clasp opens up, it’s still attached to your wrist.
2. Simple to use. You can easily attach watch to wrist with one hand.
3. Reduced wear. No need to bend the strap to fit in the buckle. Also, no wear and tear around the holes.
4. Can be more comfortable.


1. Upon purchasing, there are multiple steps to attach and fit the clasp properly.
2. The clasp can bend from pressure and create a less secure fit
3. A long deployment clasp may make the watch sit unevenly on smaller wrists.
4. More expensive than buckle.
5. Some clasps pull arm hair. 

Ardillon (Tang) Buckles

Ardillon (Tang) Buckles

The ardillon buckle, also known as a tang buckle, is the more traditional option. One end of the strap is slipped through a buckle, and a pin secures the watch to your wrist. This is the same type of buckle used on belts. 


1. Classic design
2. Flatter profile
3. Less expensive


1. Can be more difficult to attach to your wrist if you have limited dexterity.
2. Buckle can open while wearing, which can lead to your watch falling off your wrist.
3. The tang or tongue adds extra wear, especially around the holes.
