Lug width: 18mm Length: Approximately 13.5cm * when the buckle is closed. Color: Gold on the front (K14GF), silver on the back. The back also looks like a combination of colors. This is a genuine strap removed from a watch and stored at my parents' house for a long time. It appears to be unused, and while there may be some minor scratches, there are no noticeable scratches or stains, and it is clean. Please check the images carefully and agree to the above before purchasing.
