Bulova Factory Mainspring for Caravelle caliber RP - Alloy

Bulova Factory Mainspring for Caravelle 6¾ x 8 ligne caliber RP and perhaps others, #53A, 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.
