BESTFIT Mainspring 213W for Cortebert caliber 980 - Alloy

BESTFIT Mainspring 213W for Cortebert caliber 980 and suitable for Gruen caliber 290, 291 & 295 plus perhaps similar ébauche watches, white alloy, new in envelope. See image 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.
