BESTFIT Mainspring 613E for AS 970, Benrus BP & ETA 1250 - Alloy

BESTFIT Mainspring 613E for Benrus BP, AS 970 & ETA caliber 1250 movements plus perhaps similar ébauche watches, white alloy. See images for precise mainspring specifications. I 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.
