NEWALL Mainspring #1793N for AS 970, 1180, FHF (Font) 60, 601, FEF 370, 371 - Alloy

Newall alloy mainspring #1793N for AS 970, 1180, FHF (Font) 60, 601, Benrus CZ, FEF 370, 371 caliber and perhaps other similar movements, 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.
