This particular strength was made for watches that were overbanking at full wind - but that's a little deceptive because they'll work for any application that takes a 2890. I likely have several of these so the one you get may differ slightly from the images. I specialize in hard to find watch parts so I usually have whatever you might need and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.\u003c\/p\u003e","brand":"C \u0026 E Marshall","offers":[{"title":"Default Title","offer_id":47452035678516,"sku":"PMA-CEM0183S-12","price":4.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0849\/3341\/1124\/products\/1216990527.jpg?v=1705281086","url":"https:\/\/www.vintagetimeparts.com\/products\/marco-mainspring-183-for-5-0s-6-0s-elgin-factory-no-2890-steel","provider":"Vintage Time Parts","version":"1.0","type":"link"}
