See images for further (very limited) details. While it is not marked I am confident this is a \"newer\" factory Hamilton mainspring. I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. Images do an adequate but perhaps somewhat incomplete job of representing the item.\u003c\/p\u003e","brand":"Hamilton","offers":[{"title":"Default Title","offer_id":49327205155124,"sku":"PMA-HAM718010S-10","price":10.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0849\/3341\/1124\/files\/2026-10-0916.14.43.jpg?v=1791587946","url":"https:\/\/www.vintagetimeparts.com\/products\/hamilton-18s-mainspring-factory-no-14-718010-steel","provider":"Vintage Time Parts","version":"1.0","type":"link"}
