HR Mainspring #519 for Amida caliber 162 Movement - Steel

HR steel mainspring #519 for Amida caliber 162 movements and perhaps others, new in envelope. See images for precise mainspring specifications. I likely have several of these so he 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 an adequate job of representing the item.
