HR Nivastar Mainspring GA60 for AS 1302, 1315 Automatics - Alloy

HR Nivastar Mainspring with attached bridle GA60 for AS caliber 1302, 1315 automatic movements plus perhaps similar ébauche watches, white alloy, new in envelope. See images for precise mainspring specifications. I likely have several of these so the one you get may differ very 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.
