Waltham 14s Mainspring Factory No. 2210 from S. LaRose - Alloy

S. LaRose packaged (likely Swiss made) Mainspring for 14s Waltham, Factory No. 2210, alloy, new in packaging. See images for precise mainspring specifications. Don't find this one in alloy all that very frequently so grab it while you can. 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.
