BESTFIT Mainspring WI90 for International (IWC) caliber 90 - 92 - Alloy

BESTFIT Mainspring WI90 for International (IWC) caliber 90, 91, 92 movements plus perhaps similar ébauche watches, DB&H end, 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.
