AGC Phinastar Mainspring No.349 for caliber Bulova 8AZ & Unitas 200 - Alloy

AGC Phinastar Mainspring No.349 for Bulova caliber 8AZ & Unitas caliber 200 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 very 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.
