BESTFIT Mainspring 213A for Gruen caliber 210 & 211 - Alloy

BESTFIT Mainspring 213A for Gruen caliber 201, 211, 212, 291, 295, 300, 328 & Roamer 281 plus perhaps similar ébauche watches, white alloy. See image for precise characteristics. 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.
