Marco Marshalloy Mainspring 3249M for Amida 500, 501, 502, 506, 507, Peseux 170, Wittnauer 11P - Alloy

Marco Marshalloy Mainspring 3249M for Amida 500, 501, 502, 506, 507, Peseux 170, Alpina 635, 636, Wittnauer 11P caliber movements plus perhaps similar watches, white 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 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.
