BESTFIT Mainspring 213A for Gruen caliber 210, 211, 212, Roamer 281 - Alloy

BESTFIT Mainspring 213A for Gruen caliber 210, 211, 212, 290, 291, 295, 300, 328 & Roamer 281 plus perhaps similar ébauche watches, white alloy, new in possibly soiled envelope. See image 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.
