Was looking for a 5mm thick leather strap w/large buckle for my vintage seiko diver and noticed pricing for these kind of straps was extremely varied and high (depending on quality, name, blah-blah-blah). I found this item and figured I would give it a try and I was glad I did. The strap is made very well with a solid grade leather, good stitching, and solid buckle. I have a 7 inch wrist and the strap fits perfect without too much excess hanging over. Most importantly, it measures a solid 5mm thick with my calipers, and does not taper at all (22mm all the way). These same style straps go for a lot more on various watch sites (except maybe panatime.com), but overall it's a good strap that looks like it will hold up well!
