Nivaflex Mainspring for Font 120, Bulova 6AM - Alloy

Nivaflex Mainspring for Font caliber 120 & Bulova caliber 6AM plus perhaps other similar ébauche movements as well, alloy, new in envelope. See images for precise mainspring specifications. 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.
