BESTFIT Mainspring WA91 for Movado Automatic caliber 413A, 436 - 438 - Alloy

BESTFIT Mainspring WA91 for Movado caliber 413A, 436 thru 438 automatic movements, with bridle, perhaps similar ébauche watches, white alloy. 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.
