Marco Mainspring #117 for 16s Elgin 23j Motor Barrel No. 4931 - Steel

Marco Mainspring #117 for Elgin 16s 23j Motor Barrel movements, Factory No. 4931, steel, new in frail envelope. This mainspring is one of the more uncommon of Elgin mainsprings and these are covered in very sticky old Elgin grease so they need to be seriously cleaned before use. 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.
