Nivaflex Mainspring for AS 345, ETA 865 - Alloy

Nivaflex mainspring No 208 for AS caliber 345 & ETA caliber 865 plus perhaps other similar ébauche movements as well, alloy, new in envelope. See images for 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.
