NEWALL Mainspring #319N for Longines caliber 4LL, 13.15 - Alloy

NEWALL Mainspring #319N for Longines caliber 4LL & 13.15 movements plus perhaps similar ébauche watches, white alloy. See images for precise characteristics. I likely have several of these so the one you get may differ slightly from the images. 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.
