QUICK ANSWER
Watch strap fasteners in deployant folding, tang buckle, or butterfly hinged styles, securing bracelets while minimizing wear.

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.
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.
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.
