HR Nivastar Mainspring G473 for Omega 220, Bulova 10AE, 10AN, AS 1361 - Alloy

HR Nivastar Mainspring No G473 for Omega 220, Bulova 10AE, 10AN, AS 1361 & Enicar 410, 412 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 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 pretty good job of representing the item.
