Hamilton Dynavar 14/0s Factory Mainspring No. 14432 - Alloy

Hamilton Dynavar Factory Mainspring for 14/0s 17 - 19 Jewel Movements, Factory No. 14432, alloy, new in envelope. See image for precise mainspring specifications. 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 a pretty good job of representing the item.
