BESTFIT Mainspring 711P for Font 25, 251, 252 & UT 560 - Alloy

BESTFIT Mainspring 711P for Font 25, Unitas 560 and NFT 50, 51 plus perhaps other similar ébauche watches, white alloy. 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.
