Could also very well fit in other alarm and travel clocks as well. 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":48961139999028,"sku":"CMS-SPR3246BB3-12","price":8.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0849\/3341\/1124\/files\/2025-12-0616.51.59.jpg?v=1765068814","url":"https:\/\/www.vintagetimeparts.com\/products\/westclox-factory-alarm-spr-3246-bb3-80-476","provider":"Vintage Time Parts","version":"1.0","type":"link"}
