BESTFIT Mainspring WA17 for AS caliber 1477 automatic - Alloy

BESTFIT Mainspring with attached bridle WA17 for AS 1477 automatic plus perhaps similar ébauche watches (perhaps even a Bulova movement), white alloy, new in envelope. See images for precise mainspring specifications. Please check to see if your movement requires use of a separate brake. I likely have several of these so the one you get may differ slightly from the images. I specialize is 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.
