Deployment Buckle in Silver-Tone Finish, 18mm

An 18mm deployment buckle in a silver-tone finish, designed as a replacement or upgrade clasp for watch straps sized to an 18mm lug width.

The deployment buckle — sometimes called a deployant clasp — was developed in the early 20th century by Louis Cartier as an alternative to the traditional tang-and-pin buckle. Its folding mechanism distributes wear evenly across the strap, reduces the daily bending that shortens leather strap life, and adds a layer of security against accidental opening. It remains the preferred closure on many luxury timepieces.

The 18mm width fits straps cut to that lug measurement, common on dress and mid-size watches. The folding action allows the watch to be fastened and removed without threading the strap through a keeper, which suits a buyer refreshing an existing band or upgrading from a basic pin buckle to a more secure, more refined closure.
