BESTFIT Mainspring 712E for AS 1101, 1122, 1293, EB 1297 & Venus 110 - Alloy

BESTFIT Mainspring 712E for AS calibers 1101, 1122 & 1293, Bettlach 1297 and Venus 110 movements plus perhaps similar ébauche watches, white alloy, new in envelope. See image for precise characteristics. 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.
