WATCH-CRAFT Mainspring 3213W for Font 55, 72, 551, 552 - Alloy

WATCH-CRAFT Mainspring 3213W for Font 55, 72, 551, 552 caliber movements plus a plethora of similar ébauche Font variants and a huge number of Font 55 & 72 based Elgin grades (810, 811, 816, 817, 889, 890, 891, 898), white alloy, new in envelope. See images for precise mainspring specifications. 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 an adequate job of representing the item.
