NEWALL Mainspring #1316N for Aurore caliber 10 & Judex Caliber 200 - Alloy

NEWALL Mainspring #1316N for Aurore caliber 10 and Judex caliber 200, plus perhaps other similar ébauche watches, white alloy, new in envelope. See image 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 a pretty good job of representing the item.
