Sandsteel Mainspring #2208 for 16s Model 1872 movements - Steel

Sandsteel Mainspring for 16s Waltham Model 1872 movements, Factory No. 2208, steel, new. See image for precise 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.
