Marco Mainspring #332 for 12s Hampden Paul Revere & Nathan Hale #12696

Marco Mainspring No.332 for 12s Hampden Paul Revere & Nathan Hale model Pocket Watches, Factory No. 12696, steel. Could also very well fit in other watches as well. I likely have several of these so the one you get may differ slightly from the images. I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
