Because the envelope is either open or torn they're dusty so they'll need a good cleaning before, but all mainsprings should be cleaned before use anyhow. USR is short for Ulysse Sandoz-Robert of La Chaux-de-Fonds, Switzerland. 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":"USR","offers":[{"title":"Default Title","offer_id":49303730585908,"sku":"PMA-USR2222S-09","price":12.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0849\/3341\/1124\/files\/2026-09-2714.15.20.jpg?v=1790544030","url":"https:\/\/www.vintagetimeparts.com\/products\/usr-mainspring-for-waltham-18s-no-2222-steel","provider":"Vintage Time Parts","version":"1.0","type":"link"}
