BESTFIT Mainspring 2510F for Gruen calibers 405, 410, 411, 420 & 421 and ETA caliber 980 plus perhaps similar ébauche watches, white alloy. See image for precise mainspring specificaitons. 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.
