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

C&E Marshall Marshalloy Mainspring 3266M for Valjoux caliber 69 & 89 Chronographs plus perhaps similar ébauche watches, white alloy. See image for precise characteristics. 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.
