NEWALL Mainspring #1742N for Peseux 30, BFG 35 - Alloy

NEWALL Mainspring #1742N for Peseux caliber 30, Baumgartner caliber 35 plus perhaps other similar ébauche watches, alloy, 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 a pretty good job of representing the item.
