TRUFIT Mainspring for Bulova caliber 6AM - Steel

TRUFIT steel mainspring for Bulova caliber 6AM movements and likely many other similar calibers (6AH, 6AK, 6AU, 6AX, 6WM, etc.), new in envelope. See images for precise mainspring specifications. 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.
