Wittnauer Factory Mainspring caliber 5D1, 5D2, 5D3, 5D4, 5D5 bracelet movements plus perhaps similar ébauche watches as well, alloy, new in sealed packaging. 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.
