Nivaflex Mainspring for Bulova 6AH, 6AN, 6AMC, 6AHC, 6AK...- Alloy

Nivaflex Mainspring 201G for Bulova 6AN, Font 80 caliber movements plus perhaps even more similar ébauche watches (suitable for a whole ton of other Bulova calibers), alloy, new in envelope. See images for precise mainspring specifications and further details. I likely have several of these so the one you get may look different 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.
