Marco Marshalloy Mainspring 3266M for Valjoux caliber 69 & 89 Chronograph - Alloy

Marco Marshalloy Mainspring 3266M for Valjoux caliber 69 & 89 Chronographs plus perhaps similar ébauche watches, white alloy, new in envelope. See image for precise mainspring specifications and further details. 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 pretty good job of representing the item.
