BESTFIT Mainspring 613C for AS 1186 & General 90, 90A - Alloy

BESTFIT Mainspring 613C for A.S. caliber 1186 & General caliber 90 & 90A movements 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.
