HR Nivastar Mainspring G622 for ETA 2325, 2340, AS 970, 1156, Fleurier 250, Benrus CZ caliber movement plus perhaps similar ébauche watches, white alloy, new in frail or soiled envelope. See images for precise characteristics. 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.
