BESTFIT Mainspring 415A for AS 1017, Fleurier 165, Buren 60 and Universal 216 caliber wrist watch movements, alloy, new in envelope. See images for precise mainspring specifications. I likely have several of theses 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.
