NEWALL Mainspring #1734N for Aurore caliber 39 - Alloy

NEWALL Mainspring #1734N for Aurore caliber 39, plus perhaps other similar ébauche watches, white alloy, new. See image 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 a pretty good job of representing the item.
