I'll note that Borel indicates this is equivalent to a Bestfit 810H. See images for precise mainspring specifications and further details. 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 barely adequate job of representing the item. \u003c\/span\u003e\u003c\/p\u003e","brand":"BOREL","offers":[{"title":"Default Title","offer_id":49098493624628,"sku":"PMS-BOR8030QA-04","price":7.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0849\/3341\/1124\/files\/2026-04-1520.50.56.jpg?v=1776311736","url":"https:\/\/www.vintagetimeparts.com\/products\/borel-mainspring-8030-q-for-felsa-caliber-275-alloy","provider":"Vintage Time Parts","version":"1.0","type":"link"}
