BESTFIT Mainspring 4513F for Bulova 6AM, 6AH, Font 120, 64, Benrus CR, CY movements, plus perhaps similar ébauche watches, white alloy. I likely have several of these so the one you get may vary 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 a pretty good job of representing the item.
