Perlon strap is a watch strap that is made out of the synthetic fibre nylon. Nylon strap have been used by athletes, law enforcement officers and military personnel for years due to their impressive strength, and the Perlon strap is the latest evolution in the nylon watch band.

To produce nylon, the fibres are made into loops that are then locked together to form long chains. This unique construction makes Perlon more flexible than other types of nylon. It also enhances the strength of the material without adding extra weight. Like a leather watch strap, a Perlon strap typically fastens with a buckle. Often, the straps are plaited, so that their buckle pin can simply be inserted anywhere through the strap rather than through pre-cut holes, providing a greater range of sizing options with extra customization.
