Marco Mainspring #228 for Waltham 16s No. 2218 / 2267 - Alloy

Marco Mainspring No. 228 for Waltham 16s movements, Factory No. 2218 / 2267, alloy, new in envelope. The P/N is hand marked and probably should have been 228P but still close enough. See image for further details. 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
