Thank you for looking. This item is a GS Grand Seiko Leather band strap and D-buckle set. The color is khaki. (Please check the color in the photo) The lug width (the width where the band joins the watch) is 22mm. It is a non-sale item received as a novelty when purchasing the SLGH005 (Shirakaba) and is unused. The embossed pattern on the belt is a special leather strap that matches the birch tree pattern on the dial. I received it, but I don't think I'll be using it, so if you're interested, please consider this opportunity. Regarding installation, I believe the nearest watch shop will be able to replace it for a fee. We do not accept returns or exchanges to prevent fraud. Although this is a new, unused item, please be aware that it is a used item that has been stored at home. Color...Khaki系
