BESTFIT Mainspring 411P for Buren 1420, 142, 1422, UTC 29 - Alloy

BESTFIT Mainspring 411P for Buren 1420, 1421, 1422 & UTC 29 caliber movements, plus perhaps similar ébauche watches, white alloy, new in envelope. See image for precise mainspring specifications. I likely have several of these so the one you get may differ 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.
