BESTFIT Mainspring with attached bridle WA6 for Gruen caliber 480 Automatic plus perhaps similar ébauche watches, white alloy, new in envelope. See image for precise mainspring specifications. I likely have several of these so the one you get may differ slightly from the images. I specialize is 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.
