Marco Mainspring #3304 for Omega R11S, ETA 1216, Bulova 5AD, 5AH, Buren 60 - Steel

Marco Mainspring No. 3304 for Omega R11S, ETA 1216, Bulova 5AD, 5AH, Buren 60, Wittnauer 5JH, 9RW caliber movements, and perhaps other similar ébauche watches, steel, new in envelope. See images for precise mainspring specifications. Note please is says Omega R 13.15 which is a typo. I likely have several of these so the one you get may differ slightly from the images. I specialize is hard to find watch parts so I usually have whatever you might need and all watch parts are unconditionally guaranteed. Images do an adequate job of representing the item.
