Waltham Factory Mainspring - Waltham 2218 (Hole) for 16s Model 1888 - Steel

Waltham Factory Mainspring Factory No. 2218 - Hole - for 16s Model 1888 and perhaps others, Steel, new in frail envelope. See image for precise characteristics. These were available in a couple of different strengths and those that I can supply can be found in the drop-down list. I likely have several of these so the one you get may differ slightly from the images. I specialize is hard to find watch parts and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
