NEWALL Mainspring #131N for Omega caliber 241, T1S, 172 & Gruen 270,271,272 - Alloy

Newall Mainspring #131N for Omega caliber 241, T1S, 17.2 and Gruen 241, 242, 272 plus perhaps similar ébauche watches, steel, new in frail envelope. See images 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.
