This is a crocodile leather strap from a BVLGARI Gerald Genta Octo watch. It was attached to the watch, so there are some marks, but it's practically unused. Matte crocodile alligator leather watch strap, 28mm width. - Material: Genuine leather (alligator), matte black - Width: 28mm - Features: Genuine Alligator stamp - Compatible models: OBR.Y.50.510.CN.BD. I believe it will fit all 28mm Octo models. Please refer to the third attached image for details.
