Waltham Factory Mainspring for Model 670 Watches No. 2261 / 2244 - Alloy

Waltham Mainspring for Model 670 movements, Factory No. 2261 alloy, new in envelope. This is the equivalent of a 2244 when in steel. These were available in a couple of different strengths and those that I can supply are shown in the drop-down 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.
