Bulova Factory Mainspring for Caravelle caliber 16OA Pocket Watch - Alloy

Bulova Factory Mainspring for Caravelle caliber 16OA Pocket Watch movements, which are Unitas 6497/6498 caliber based, 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 a pretty good job of representing the item.
