This is not the first time I've run across a mainspring that Waltham made for a competing maker and I don't get the sense that they did as much finishing on these as they did the ones they made for their watches, but it's still a fine NOS mainspring. I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. Images do an adequate but perhaps incomplete job of representing the item.\u003c\/p\u003e","brand":"Waltham","offers":[{"title":"Default Title","offer_id":48909800472884,"sku":"PMA-ROW0822S-10","price":12.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0849\/3341\/1124\/files\/2025-10-0113.44.41.jpg?v=1759351644","url":"https:\/\/www.vintagetimeparts.com\/products\/rockford-16s-mainspring-no-822-made-by-waltham-steel","provider":"Vintage Time Parts","version":"1.0","type":"link"}
