What does

Clasp (Deployant, Tang, Butterfly)

mean?

A clasp is a crucial component of a watch strap or bracelet, designed to secure the watch on the wearer's wrist. There are several types of clasps, each offering unique features and benefits.

The deployant clasp, also known as a deployment clasp, is a popular choice for its ease of use and added security. It consists of a folding mechanism that allows the strap to open and close smoothly, reducing wear and tear on the leather or metal band. This type of clasp is favored for its ability to maintain the watch's fit and prevent accidental drops.

The tang clasp, often referred to as a buckle, is similar to a traditional belt buckle. It involves a pin that fits into a series of holes on the strap, allowing for adjustable sizing. Tang clasps are commonly found on leather and fabric straps, offering a classic and straightforward fastening method.

The butterfly clasp is a sophisticated option that provides a seamless look. It features two hinged wings that open and close like a butterfly's wings, ensuring a secure fit while maintaining the aesthetic of the watch bracelet. This clasp is particularly favored for metal bracelets, as it offers a clean, uninterrupted appearance when closed. Each clasp type enhances the functionality and style of a watch, catering to different preferences and needs.

Frequently Asked Questions

What's the difference between deployant and tang buckle?

A deployant clasp folds open with hinged arms, keeping the strap in one piece when removed, reducing wear on leather. Tang buckles work like belt buckles with a pin through holes, simpler but causing more stress on the strap material over time. Deployants are premium.

Why do metal bracelets use butterfly clasps?

Butterfly clasps (also called deployant clasps for bracelets) fold symmetrically from both sides, distributing tension evenly and maintaining the bracelet's appearance when closed. They're more secure than tang clasps, prevent bracelet twist, and eliminate visible buckle hardware, creating a seamless look on metal bracelets.

Can you replace a tang clasp with a deployant?

Yes, but it requires purchasing a deployant clasp matching your strap width (18mm, 20mm, etc.) and type (leather, rubber, NATO). The original strap may need shortening since deployants take up more length. Most straps with tang buckles can be converted to deployant relatively easily.
