Rezista Mainspring #148 for Bulova 8AH, 8AP, 8WH, Benrus AX, ETA 1000 - Steel

Rezista mainspring #148 for Bulova 8AH, 8AP, 8WH, Benrus AX, ETA 1000, AS 962 caliber movements 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.
