NEWALL Mainspring #1701N for Cyma 484, 486, Oris 654 - Alloy

Newall N-Dur-All Mainspring #1701N for Cyma 484, 486, Oris 654 caliber movements plus perhaps similar ébauche watches, alloy, GR Ref. 3750, 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.
