Nivaflex Mainspring for AS 1200, ETA 825 - Alloy

Nivaflex mainspring for AS 1200, ETA 825 caliber movements plus perhaps other similar ébauche movements as well, white alloy, new in envelope. See images for further data and precise mainspring specifications. 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.
