ISOFLEX Mainspring for A.S. 976 & 1012 - Alloy

IOSFLEX Mainspring for AS 976, 1012 and many similar ébauche watches, white alloy. Even though the box says 1/2 douz I just have the one left so you are getting just the one. See image for precise characteristics. 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.
