This is an 11mm leather strap for a SEIKO CREDOR watch. The CREDOR mark pattern is on the back. The buckle has the CREDOR engraving on the inside. Even to the untrained eye, the buckle's shape has more intricate detailing and a beautiful finish compared to other straps I have at home. There are no visible scratches, stains, or pin marks in the holes, so I believe it's probably unused. However, I'm not sure of its usage history, so I'll assume it's been used less than 10 times.
