Waltham Factory Mainspring for 22s 8 Day No. 2245 - Steel

Waltham Factory mainspring No. 2245 for 22s 8 day movements, steel, new in envelope. See image for further information. I likely have several of these so the one you get may differ slightly from the images. These came in a couple of different strengths and those that I can supply are shown in the drop-down list. 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.
