New, unused Seiko genuine D-buckle, SEIKO logo, buckle width 18mm, three-fold push-button buckle, silver (mirror finish) B16S51SA02W-R. 《SEIKO Description》 SEIKO Seiko D-buckle 18mm Stainless Steel Silver Mirror Finish B16S51SA02W-R Genuine Parts This product is a domestic genuine product. Seiko Watch Genuine Parts D-buckle B16S51SA02W-R Buckle width 18mm Made of stainless steel Silver Mirror finish Purchased new. Opened for photography and content confirmation. I think it's perfect for Grand Seiko. The buckle side of a Grand Seiko (GS) leather strap with a lug width of 20mm is usually 18mm, but please be sure to check the size of the buckle on your leather strap before purchasing. It cannot be installed if it is not 18mm. D-buckles with the GS logo cost 30,000-40,000 yen, but this SEIKO logo is also sufficient for Grand Seiko. The impression after opening it is that it is very sturdy and will match Grand Seiko very well. If you look closely, a transparent protective seal is attached to a part of the buckle. Please check the photos. Although it is a new, unused item, it has been opened, so please refrain from purchasing if you are concerned. Reference price: 10,000 yen. How about it for Seiko fans, as well as Rolex and Omega fans?
