Marco Marshalloy Mainspring 5020M for Wittnauer 11AR, 11ARK, AS 1361, 1402 Automatic - Alloy

Marco Marshalloy Mainspring 5020M for Wittnauer caliber 11AR, 11ARK Automatic movements and AS caliber 1361, 1402 automatic movements, and perhaps others as well, alloy, new in envelope. I likely have several of these so the one you get may differ slightly from the images. 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.
