What is Watch Strap Clasps

Watch strap clasp is a device that used to secure the watch strap around the wrist. It ensures that the watch stays in place and provides a comfortable fit for the wearer. Watch strap clasps come in various designs and mechanisms, each offering its own advantages and aesthetics. The choice of a watch strap clasp depends on personal preference, watch style, and desired functionality. In this post, Handdn will guide you to choose which clasp suitable for your watch strap.

Types of Watch Strap Clasps

Pin Buckle (Tang Buckle)

The Pin buckle, also commonly referred to as the Tang buckle, is a classic and timeless watch strap clasp. Known for its simplicity and reliability, this traditional clasp design has stood the test of time. The tang buckle features a simple design consisting of a pin and tang. The pin, attached to one end of the strap, slides through holes or slots on the other end, while the tang secures the strap in place. This uncomplicated mechanism makes the tang buckle easy to use and adjust, allowing for a secure and comfortable fit on the wrist.

With multiple holes or slots on the strap, you can easily find the perfect fit for your wrist size. Tang buckles are typically crafted from high-quality materials such as stainless steel, titanium, or precious metals like gold or silver. These robust materials ensure the clasp’s durability and longevity, making it resistant to wear and tear.

Butterfly Clasp

A Butterfly watch strap clasp, also known as a hidden clasp, is a type of watch clasp that named after its resemblance to the wings of a butterfly when opened. The butterfly clasp consists of two hinged metal plates that fold over the strap and lock into place. The mechanism is hidden, giving the clasp a clean and seamless appearance when closed. It typically operates with a push-button release mechanism. When the button is pressed, the clasp opens, allowing for easy putting on and taking off of the watch. The clasp securely locks into place when released, ensuring that the watch remains securely fastened on the wrist.

In terms of comfort, the butterfly clasp offers a smooth and comfortable fit. The hidden mechanism eliminates any sharp edges or protrusions that could pinch or irritate the skin. The weight of the watch is distributed evenly across the wrist, reducing pressure points and enhancing comfort during extended wear.

In terms of durability, butterfly clasps are generally well-made and reliable. They are designed to withstand regular wear and tear and offer a secure closure to keep the watch in place. However, it is important to ensure that the clasp is made from high-quality materials to ensure its long-term durability.

Deployant Clasp

The Deployant Clasp design consists of two separate parts: a folding metal buckle and a hinged extension piece. Unlike traditional tang buckles, which rely on a pin and holes to fasten the strap, the deployant clasp features a locking mechanism. With its folding mechanism, the clasp can be easily opened and closed with one hand, eliminating the need to struggle with traditional buckle designs. This feature is particularly beneficial for individuals with limited dexterity or those who frequently remove and wear their watches.

This mechanism typically includes a push-button release or a hidden deployment system that ensures the clasp remains securely closed during wear. This added security reduces the risk of accidental openings and prevents the watch from slipping off the wrist. The hinged extension piece in the clasp enables easy size adjustments, accommodating different wrist sizes without the need for additional holes in the strap.


Picking the right clasp for your watch strap is important for both how it works and how it looks. Think about things like how comfortable and secure it is, if you can adjust it easily, and what kind of style you want. When you buy watch straps from Handdn, you’ll get a tang buckle for free!
