BESTFIT mainspring 34Y for Bulova 17AH, ETA 953, Font 33 to 37, Benrus AW caliber movements plus perhaps other similar ébauche movements as well, 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 an adequate job of representing the item.
