Waltham Factory Mainspring for Model 670 Watches No. 2244 - Steel

Waltham Mainspring for Model 670 movements, Factory No. 2244 steel, new in envelope. See images for further details. These were available in a couple of different strengths and those that I can supply can be found in the variations list. I specialize in hard to find watch parts so I usually have whatever you might need and all watch parts are unconditionally guaranteed. See image for further details. Images do a pretty good job of representing the item.
