BESTFIT Mainspring 612C for Lengme 810, MST 358, 359, 273 - Alloy

BESTFIT Mainspring 612C for Lengme caliber 810 and MST caliber 358, 359, 273 movements plus perhaps similar ébauche watches, 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.
