BESTFIT Mainspring 511H for Bulova 9AN, MST 317, Cyma-Tavannes 110 & 111, Jeambrun 23D caliber movements 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 (and they're all marked slightly differently). 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.
