NuTemper Mainspring #593 for Waltham 6/0s Jewel Series Factory No. 2235 - Steel

NuTemper Mainspring #593 for Waltham 6/0s Jewel Series, Factory No. 2235, steel, new in envelope. See images for precise mainspring specifications. I likely have several of these so the one you get may differ slightly from the images. I specialize is hard to find watch parts and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
