BESTFIT Mainspring 610P for Font caliber 200 - Alloy

BESTFIT Mainspring 610P for Font caliber 200 plus perhaps similar ébauche watches (including several ETA movements), white alloy, new in envelope. See images 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.
