Nice matte or satin finish stainless steel watch strap buckle -- a difficult type to find. This is a New Old Stock vintage watch strap buckle stamped Stainless Steel. Buckle size is 16mm, so it will fit straps that have a 16mm buckle end (often these are straps with 18mm 19mm 20mm or 22mm lug end sizes). It has a flat, unpolished satin top finish. Top to bottom clearance of this buckle is 7.2mm, so this buckle will work with lightly padded or unpadded straps only. Nice shape. Buy with confidence from a seller on EBAY since 1998 with 20,000 positive feedbacks and a member of the NAWCC watch collector's association since 1997.
