Here are five watch straps. They are no longer needed as I've replaced them. All are 20mm, genuine SEIKO. There are scratches and wear overall. The two on the left have SEIKO markings on the back of the buckle. The second from the left is titanium (see the last image). These would be suitable for those who have many watches, those who use them for resale or maintenance, or those who want to resell them individually.
