BOREL Mainspring A4026-W for Tissot caliber 28 and variants - Alloy

BOREL Mainspring A 4026-W for Tissot 28 and variants 28.1, 28.21 caliber movements plus perhaps similar ébauche watches, white alloy, with brake, 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 barely adequate job of representing the item.
