Waltham 6s Mainspring Factory No. 2215 / 2217 from S. LaRose - Alloy

S. LaRose packaged (likely Swiss made) Mainspring for 6s Waltham, Factory No. 2215 / 2217, alloy, new in package. See images for further details and precise mainspring specifications. I 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 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.
