Sandsteel Mainspring for 6s Waltham No. 2219 - Steel

Sandsteel Mainspring for 6s Waltham Movements, Factory No. 2219, steel, hole end, new in envelope. See images for precise mainspring specifications. These came in a couple of different strengths and those that I can supply can be found in the drop-down list. I also likely have several of these so the one you get may differ very slightly from the images. I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
