HR Quick Fit Mainspring KA65 for AS caliber 913, 1171, 1173 - Alloy

HR Quick Fit Mainspring KA65 for AS 913, 1171, 1173 caliber movement plus perhaps similar ébauche watches, white alloy, new in sealed envelope. 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 an acceptable job of representing the item.
