HR Nivastar Mainspring G570A for Bulova 10BA, 10BE, 10ZE, ETA 900, AS 1280, Durowe 410, 412 caliber 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 an adequate job of representing the item.
