Archer Watch Straps' stainless steel replacement buckles come in a variety of colors and finishes so you can match your watch with any strap that takes a 16mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, or 24mm buckle. Be sure to measure the buckle width and not just the strap width since many watch bands are tapered. They are easy to install and change - just insert a pin or pointed spring bar tool into the hole on the side of the buckle to release the spring bar. Each buckle comes with both 2mm and 3mm wide tongues in order to be compatible with straps that have different size holes. Money back guarantee if you are not satisfied for any reason.
