See images for further details. Measures 4.7mm x .205mm or thereabouts. I likely have several of these so the one you get may differ slightly from the images. I sell a fine reprint of the factory parts and assembly catalog for this model of Alarm Clock if you need it, just check my other listings. I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. Images do a barely adequate job of representing the item.\u003c\/p\u003e","brand":"Westclox","offers":[{"title":"Default Title","offer_id":49073020436788,"sku":"CMS-SPRA1033S-03","price":8.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0849\/3341\/1124\/files\/2026-03-2716.12.57_158ac724-e6c8-4915-a72c-f7f2387d5bce.jpg?v=1774653444","url":"https:\/\/www.vintagetimeparts.com\/products\/westclox-factory-alarn-clock-mainpring-spr-a-1033","provider":"Vintage Time Parts","version":"1.0","type":"link"}
