BESTFIT Mainspring 413E for Bulova 10AC, 10AT and Font 32 - Alloy

BESTFIT Mainspring 413E for Bulova 10AC, 10AT and Font 32 plus perhaps similar ébauche watches, white alloy, new in faded envelope. I likely have several of these so the one you get may vary slightly from the images. See image for precise characteristics. 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.
