Thank you for your interest in the product. [Parts] Calf Embossed Strap 13mm Dark Brown This item was kept in a desk drawer, inside a plastic bag. Sizes are: Buckle side body: 65mm Hole side: 110mm Buckle width: 10mm Attachment width: 13mm I purchased this for a Grand Seiko ladies' watch, but I have never used it. It looks black in the photos, but as you can see in the last image, you can tell the difference when compared to a black strap. The manufacturer is unknown. *The black strap is not included. I recommend this product to those who have read the profile section and understand the above, and to those who are looking for a ladies' strap, a Grand Seiko strap, or a 13mm wide strap, and to those who are interested in the product. Color: Brown
