Bulova factory Buloloy Insertopak Mainspring for caliber 11AFC - Alloy

Bulova Buloloy Insertopak Mainspring for caliber 11AFC, alloy, new in package. See images for further details. The wonderful thing about factory mainsprings is they always fit. I likely have several of these so the on 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 an adequate job of representing the item.
