I know it says 2528 but the \"newer\" factory number is 22528, and honestly these are pretty hard to find as South Bend didn't make that many 0s watches. I likely have several of these so the one you get may differ slightly from the images. I check these older mainsprings carefully before I list them all watch parts are unconditionally guaranteed. Images do an adequate job of representing the item.\u003c\/p\u003e","brand":"USR","offers":[{"title":"Default Title","offer_id":47451954184500,"sku":"PMA-USR2525S-09","price":4.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0849\/3341\/1124\/products\/1214840992.jpg?v=1705277567","url":"https:\/\/www.vintagetimeparts.com\/products\/usr-mainspring-south-bend-0s-no-22528-steel","provider":"Vintage Time Parts","version":"1.0","type":"link"}
