This is the TIME side mainspring in steel and is suitable for caliber 942, 949-8 and 249 although there are better matches for the latter caliber than this mainspring. Could also very well fit in other travel \u0026amp; Alarm clocks. See images for precise mainspring specifications. I likely have several of these so the one you get may differ slightly from the images. Images do a suitable job of representing the item.\u003cbr\u003e\u003c\/p\u003e","brand":"Excelsior","offers":[{"title":"Default Title","offer_id":48941218758964,"sku":"CMS-EXC2960S-11","price":7.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0849\/3341\/1124\/files\/2025-11-0721.22.33.jpg?v=1762579395","url":"https:\/\/www.vintagetimeparts.com\/products\/excelsior-2960-time-mainspring-for-imhof-alarm-travel-clocks","provider":"Vintage Time Parts","version":"1.0","type":"link"}
