HR Quick Fit Mainspring K264 for ETA 953, Font 35, Bulova 17AH - Alloy

HR Quick Fit Mainspring K264 for ETA caliber 953, Font caliber 35, Bulova caliber 17AH and Benrus AW movements plus perhaps similar ébauche watches, white alloy, new in envelope. See image for precise mainspring specifications.  My experience with the mainsprings Quick Fit made for larger movements is the easy insertion claims are usually not possible because of a different keeper.  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.
