BESTFIT Mainspring 211H for Bulova 6T, 6AT, 6TAA, Gruen 117, 119, 1158, 1159 - Alloy

BESTFIT Mainspring 211H for Bulova caliber 6T, 6AT, 6TAA, Gruen 117, 119, 1158, 1159 caliber movements and quite likely others, alloy, 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.
