BESTFIT Mainspring 310H for Gruen caliber 807, 808, 809, 816 and A.S. caliber 525, 588 plus perhaps similar ébauche watches, white alloy. 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.
