BESTFIT Mainspring 4514C for Mido 717, AS 1236 - Alloy

BESTFIT Mainspring 4514C for Mido 717, AS caliber 1236 (and perhaps AS 1977) plus perhaps similar ébauche watches, 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.
