Nivaflex Mainspring for Waltham 6/0s No. 2226 - Alloy

Nivaflex Mainspring for 6/0s Waltham movements, Factory No. 2226, alloy, new in envelope. See image 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.
