HR Nivastar Mainspring G414 for ETA 1201, 1316, Felsa 705, 70, Roamer 401, 411 caliber movements plus perhaps similar ébauche watches, alloy, new in envelope. I likely have several of these so the one you get may differ slightly from the images. See images for precise mainspring specifications. 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.
