Waltham Factory Mainspring for 6s & 8s 1873 Model No. 2215 - Steel

Waltham Factory Mainspring for 6s & 8s Model 1873 Movements, Factory No. 2215, steel, new in likely frail envelope. See images for further details. I likely have several of these in different strengths and those that I can supply will be shown in the drop-down list. That said, this can be a very difficult mainspring to find so grab them 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.
