Marco Mainspring No. 2953 for Bulova caliber 9AN, 10AC, 10AT, ETA 785 - Steel

Marco No. 2953 steel mainspring for Bulova caliber 9AN, 10AC, 10AT, ETA caliber 785 plus some older 10¾ ligne AS and 9¾ ligne Font movements, and perhaps even more as well, 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 is 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.
