Hamilton Mainspring for 14/0s Hamilton 980, 982, etc. No. 717440 - Alloy

Hamilton Mainspring for 14/0s Movements, Factory No. 717440, alloy, new in envelope. A newer generic repackaging of what is most likely a Swiss made mainspring, correctly marked as fitting the grade 982 (and others). I likely have several of these so the one you get may differ slightly from the images. I specialize is hard to find watch parts and all watch parts are unconditionally guaranteed. Images do an adequate job of representing the item.
