BESTFIT Mainspring 6511J for Rolex A295, ETA 900, 1080 Benrus BA-BB, Bulova 10BE - Alloy

BESTFIT Mainspring 6511J for Rolex A295, Eta 900, Bulova 10BE, Benrus BA-BB and ETA caliber 900, 1080 movements plus perhaps similar ébauche movements, white alloy, new in envelope. See images for precise mainspring specifications. I likely have several of these so the one you get may differ 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.
