BESTFIT Mainspring 5595M for Felsa 400, 465 - Alloy

BESTFIT Mainspring 5595M for Felsa 400, 465 caliber movements plus perhaps similar ébauche watches, alloy, new in envelope. I likely have several of these so thew one you get may differ slightly from the images. See images for precise specifications. 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.
