Just received and installed on Seiko 5 that had an awful nylon strap. The Berfine strap is very thick quality leather with nice stitching. It came with spring bars and a stainless barrel type bushing that goes between the leather and spring bar , GREAT IDEA !! I would have given 5 stars but Im not thrilled with stitching color although very nicely done its kind of beige and the picture on Amazon is white. Very nice band easy to install
