R.U.N Eternipower Mainspring A934 for Felsa caliber 700, 705 - Alloy

R.U.N Eternipower Mainspring A 934 for Felsa caliber 700, 705 caliber movements plus perhaps similar ébauche 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 barely adequate job of representing the item.
