BESTFIT Mainspring 314AA for Gruen 275, 280, Felsa 197 & Cyma 433, 434 - Alloy

BESTFIT Mainspring 314AA for Gruen 275 & 280, Felsa 197 & Cyma 433, 434 caliber movements plus perhaps 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 a pretty good job of representing the item.
