Swartchild Black Shield SUPER Mainspring for Bulova 8AL, AS 970 - Alloy

Swartchild Black Shield SUPER Mainspring for Bulova caliber 8AL, AS caliber 970, Clinton 8¾ ligne movements and numerous similar ébauche watches, white 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.
