HR Quick Fit Mainspring K610 for Bulova 10BC, 10BS, Witt 10E, 10S, ETA 1280 - Alloy

HR Quick Fit Mainspring K610 for Bulova 10BC, 10BS & Wittnauer 10E, 10S, ETA 1280 and AS 1187, 1194 plus perhaps similar ébauche watches, white alloy. See images for precise characteristics. 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 a pretty good job of representing the item.
