LeCoultre Factory Mainspring for caliber 8NR, 496 - Alloy

LeCoultre Factory Mainspring for caliber 8NR, 8RF, 8RFO, 496, alloy, new in open package. The wonderful thing about factory mainsprings is they always fit. The package contains the mainspring and a connector for the end. 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.
