Samson No. 3085 steel mainspring for Cyma / Tavannes 90, 91, 98, 99 caliber movements and others as well, 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.
