HR Nivastar Mainspring G612 for Buren 380 to 383, Movado 150 MN - Alloy

HR Nivastar Mainspring G612 for Buren 380, 381, 382, 383 and Movado 150 MN caliber movement plus perhaps similar ébauche watches, white alloy. 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.
