Marco Mainspring #2741 for Gruen caiber 802SS, 803SS - Steel

Marco No. 2741 steel mainspring for Gruen 802SS, 803SS caliber 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 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.
