BESTFIT Mainspring JA708 for 16s Waltham Factory No. 2208 - Alloy

Bestfit Mainspring MS-JA708 for 16s Waltham, Factory No. 2208, alloy, new in envelope. See images for precise mainspring specifications. 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.
