Swisscraft Mainspring A-124 for 7¼L Waltham No. 2238 - Steel

Swisscraft Mainspring A-124 for Waltham 7¼ Ligne Movements, Factory No. 2238, steel, 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 and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
