See images for further details. This is not an easy mainspring to find and while the 812 may function similarly it's likely way too strong for a properly adjusted 21j and 23j movement, which is what this mainspring is for. I likely have several of these so the one you get may differ slightly from the images. I specialize is hard to find watch parts and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.\u003c\/p\u003e","brand":"Swartchild","offers":[{"title":"Default Title","offer_id":47452042527028,"sku":"PMA-SWA4354S-08","price":18.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0849\/3341\/1124\/products\/1241688758.jpg?v=1705281364","url":"https:\/\/www.vintagetimeparts.com\/products\/swartchild-black-shield-mainspring-for-elgin-18s-2446-2096-steel","provider":"Vintage Time Parts","version":"1.0","type":"link"}
