Marco Mainspring #3162A for Pierce caliber 134 Chronograph - Steel

Marco Mainspring No. 3162A for Pierce caliber 134 Chronograph movements plus perhaps similar ébauche watches, steel, new in envelope. See images for precise mainspring specifications. 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.
