BESTFIT Mainspring WA24 for AS caliber 1716, 1717 Automatic - Alloy

BESTFIT Mainspring WA24 for AS caliber 1716, 1717 automatic movements, white alloy, new in dirty envelope. See images for precise mainspring specificaions. 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.
