Waltham Mainspring for 6/0s Model 1912 Jewel Series movements, Factory No. 2235, steel, new in envelope. See images for further details. These are available in different strengths and those that I can supply are shown in the drop-down list 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 and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
