This is a SEIKO watch strap with a lug width of 13mm. It's a long-term stock item from a watch store, so the box is old, but the contents are new and unused. It suits old SEIKO watches well. - Brand: SEIKO - Material: Stainless steel - Size: 13mm lug width Thank you for viewing. Please feel free to ask any questions. Thank you. #WatchStrap #13mm #SEIKO
