A watch strap or watch bracelet is a strap or bracelet that holds a wrist watch to the wrist. Watch straps may be made of leather, plastic, rubber, cloth, or metal, sometimes in combination. It can be regarded as a fashion item, serving both a utilitarian and decorative function. Some metal watch straps may be plated with, or even in rare cases made of, precious metals.
Watch straps may close with a buckle or a butterfly clasp. Expanding watchstraps are designed to expand elastically, often by the use of metal springs in a segmented design, and may be slipped on like a bracelet. Attachment points for the strap to the watch are largely standardized, with a spring-loaded double-ended pin used to anchor the watch strap to holes in a bracket that is integral to the watch case, allowing worn watch straps to be replaced or swapped with new straps for fashion purposes.
