NEWALL Mainspring #1883N for Angelus caliber 210 to 217 - Alloy

Newall N-Dur-All Mainspring #1883N for Angelus caliber 210, 211, 212, 213, 214, 215, 217 movements plus perhaps similar ébauche watches, alloy, GR Ref. 5020, 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.
