Diashock 25 Jewels, ダイアショック 25石, SS Stainless Steel This item was purchased by my grandfather a long time ago and used by him. It has been stored at home for a long time. I was able to confirm that it works when hand-wound. Time adjustment was also possible using the crown. Due to wear, it's difficult to read in the photos, but the back cover is engraved with "Seiko Goldfeather 15005 E STAINLESS STEEL". There is no belt or case. I am not very knowledgeable about watches, so it is difficult to provide information other than this, but please let me know if you have any questions or if you would like additional photos.
