Bulova Factory Mainspring w/ bridge for Caravelle caliber 7OBAC - Alloy

Bulova Factory Mainspring w/ bridge for Caravelle caliber 7OBAC and perhaps others, #53AS, alloy, new in sealed package. The wonderful thing about factory mainsprings is they always fit. 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.
