Marco Marshalloy Mainspring 3083M for Valjoux 22, 71, Benrus GH, ETA 704E Chronograph - Alloy

Marco Marshalloy Mainspring 3083M for Valjoux caliber 22, 71, Benrus GH, ETA 704E, Tavannes 400L Chronograph 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 an adequate job of representing the item.
