Samson Mainspring No. 8108 for Imperial 0s Pendant Pocket Watch - Steel

Samson No. 8108 steel mainspring for Imperial 0s Pendant Pocket Watch and perhaps others, 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 an adequate job of representing the item.
