BESTFIT Mainspring 8512F for Lapanouse caliber 301, 302, 303 - Alloy

BESTFIT Mainspring 8512F for Lapanouse / Cimier caliber 301, 302, 303 movements plus perhaps similar ébauche watches, white alloy, new in envelope. See images for precise mainspring specification. 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.
