Watch Clasps

Clasp Compatibility Info

Please make sure to select the correct size and model clasp to fit your strap. The clasp size needed for your strap is usually different from the strap size. For example, a 20mm strap usually tapers by 2mm to 18mm at the clasp end and would require an 18mm clasp and not a 20mm clasp as you may assume. Also, not all clasps are compatible with all straps. Our most widely compatible clasp is our butterfly deployant clasp. Please contact us if you have any questions about buckle compatibility.

Frequently Asked Questions

What are watch clasps?

These are bracelet closures that allow a watch band to be opened and locked close. They are usually made for stainless steel bands, which is a commonly used material for most casual and elegant watches. Almost all popular timepiece brands use these locks to secure their watches to the wrist.

What are the different types of watch clasps?

There are several types of watch clasps used in the market today. The most common ones are the following: 

  • Deployment clasp – This closure works by folding out when opened through a built-in latch mechanism. It’s a common type of buckle used by many timepiece manufacturers today.
  • Deployment with safety – Unlike the regular deployment type, this closure has an extra fold-over layer after safely locking in place. This is an added security that most prestigious watch brands use.
  • Butterfly clasp – Also known as a hidden clasp, this closure opens at both ends of the band. When opened, it resembles the wings of a butterfly, which explains its name. Many premium manufacturers use this type as it provides a seamless look to the watch band when closed.
  • Push-button butterfly –  This is similar to the butterfly closure, only that it uses a push-button mechanism to easily open the band. 
  • Buckle – The buckle type is common among straps with softer materials, such as leather or canvas. Similar to a belt closure, it uses a loop and pin to secure the bracelet strap.
