Hamilton Factory Dynavar Mainspring for 22/0s Hamilton No. 32434 - Alloy

Hamilton Factory Dynavar Mainspring for 22/0s Movements, Catalog No. 32434, alloy, new in envelope. Made for Grades 911 & 911M, and perhaps others. See image for precise characteristics. 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.
