NEWALL Mainspring #1100N for Omega caliber 540 - Alloy

Newall Mainspring #1100N for Omega caliber 540 plus perhaps similar ébauche watches, alloy, GR Ref. 2000, 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.
