Bulova Factory Mainspring for caliber 6EA - Steel

Bulova Factory Mainspring for caliber 6EA and perhaps even more similar ébauche watches, steel, new in envelope. See images for further details and any other supported calibers. The wonderful thing about factory mainsprings is they always fit! 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.
