BESTFIT Mainspring WL11 for Longines caliber 23M plus perhaps similar ébauche watches, alloy. See images for precise mainspring specifications. I likely have several of these so the one you get may differ very 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.
