HR Quick Fit Mainspring K430 for Font 64, 120, Bulova 6AH & 6AM, Benrus CR & CY 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 vary 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.
