BESTFIT Mainspring WL5 for Longines 8LN & Wittnauer 6FF, 6FS, 6FA - Alloy

BESTFIT Mainspring WL5 for Longines caliber 8LN and Wittnauer caliber 6FF, 6FS, 6FA plus perhaps similar ébauche watches, white alloy. See image for precise characteristics. I likely have several of these so the one you get may differ 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.
