LeCoultre Factory Mainspring for caliber 12AD / 481 - Alloy

ONE LeCoultre Factory Unbreakable Mainspring for caliber 12AD / 481, alloy, new in open 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.
