Samsonspring Mainspring No. 82 for Elgin 16s No. 817 - Steel

Samsonspring No. 82 steel mainspring for Elgin 16s movements, Factory No. 817, 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 in hard to find watch parts so I usually have whatever you might need and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
