WATCH-CRAFT Mainspring 3551W for Bulova caliber 11AFC, Buser caliber 146 - Alloy

WATCH-CRAFT Mainspring 3551W for Bulova caliber 11AFC, Buser caliber 146 movements plus perhaps others, white alloy, new in envelope. See images for precise mainspring specifications. I will note that while someone wrote this is a replacement for Bestfit 3511H, this mainspring is about an inch longer and is meant for the two movements I specified. 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.
