Tru-Time Mainspring for Bulova 8AH, Benrus AX, W & ETA 761, 1000 - Steel

Tru-Time mainspring for Bulova caliber 8AH, Benrus AX, W & ETA 761, 1000 plus perhaps other similar ébauche movements as well, steel, 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.
