BESTFIT Mainspring 6513J for Font caliber 125 - Alloy

BESTFIT Mainspring 6513J for Font caliber 125 plus perhaps similar ébauche watches, white alloy. See images for precise mainspring specifications and note the variance in mainspring length across them - they vary from about 280 to 300 which isn't a big deal, just unusual as Bestfit mainspring tend to be very consistent across manafacturing lots. 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.
