Could also very well fit in other 18s American watches too (hint, hint). 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 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":47451959066932,"sku":"PMA-CEM0301S-09","price":12.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0849\/3341\/1124\/products\/3813332805.jpg?v=1707013427","url":"https:\/\/www.vintagetimeparts.com\/products\/marco-mainspring-301-for-18s-hampden-movements-factory-no-1696-steel","provider":"Vintage Time Parts","version":"1.0","type":"link"}
