BOREL Mainspring 4513AA for Peseux caliber 140 & 290 - Alloy

BOREL Nivaflex Mainspring 4513AA for Peseux caliber 140 & 290 plus perhaps similar ébauche watches, white alloy, new in package. See images for further details. 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 a pretty good job of representing the item.
