BOREL Mainspring A4022-Q for Bulova caliber 10AUC automatic - Alloy

BOREL Mainspring A 4022–Q for Bulova caliber 10AUC automatic movements (with bridle) plus 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.
