Marco Mainspring #2829 for Peseux 10, 120, 130, 210, Aurore 17T, Benrus H, Gruen 675, MST 369, Mido 812, Blancpain 45, 46 caliber movements plus perhaps other ones as well, steel, new in envelope. See images for further data and precise mainspring specifications. 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 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.
