WATCH-CRAFT Mainspring 3536W for ETA 735, 2390 caliber movements and likely others as well, white alloy, new in envelope. See image for precise mainspring specifications. 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..
