BOREL Mainspring 6029-T for Gruen 415, 416, 422 - Alloy

BOREL Mainspring 6029-T for Gruen caliber 415, 416, 422 plus perhaps other 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 an adequate job of representing the item.
