HR Mainspring SA127 for Elgin 19/0s Factory No. 6330 - Alloy

HR Mainspring SA127 for 19/0s Elgin, Factory No. 6330, alloy, 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 satisfactory job of representing the item.
