Marco Mainspring #3360 for Baumgartner caliber 33, 34, 800 - Steel

Marco Mainspring No. 3360 for Baumgartner (BFG) caliber 33, 34, 800 movements, and perhaps others, 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.
