BESTFIT Mainspring WA51 for Movado Automatic caliber 531 - Alloy

BESTFIT Mainspring WA51 for Movado caliber 531 automatic movements, with bridle, plus perhaps similar ébauche movements, 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 a pretty good job of representing the item.
