Elgin Balance Staff for 19/0s to 21/0s Grades 655 to 700 Factory No. 6570

ONE Elgin Balance Staff for 19/0s & 20/0s, grades 655 to 700 and perhaps beyond, including Lady Elgin, No. 1653 (believe the Factory No. is 6570), new in open envelope. See images for further details. This is either an aftermarket staff or a staff repackaged by a material house. I specialize is 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.
