HR Nivastar Mainspring G552 for Cyma 404, ETA 865 & Pierce 100 - Alloy

HR Nivastar Mainspring No G552 for Fleurier 86, 170, Cyma 404, Eta 865 & Pierce 100 caliber movements plus perhaps other watches as well, alloy, new in envelope. See images for further data and precise mainspring specifications. I likely have several of these so the one you get may different 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 an adequate job of representing the item.
