NEWALL Mainspring #1606N for Venus 130, Gruen 679, 680, 681, 682, 690, 691 - Alloy

NEWALL Mainspring #1606N for Venus 130 and Gruen 679, 680, 681, 682, 690, 691 caliber movements plus perhaps other similar ébauche watches, white 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 an adequate job of representing the item.
