Waltham Factory Mainspring for Model 678 - 679 Movements No. 2251 - Steel

Waltham Mainspring for Model 678-679 movements, Factory No. 2251, 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 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.
