Sandsteel Sandalloy Mainspring S3261 for Bulova 6F, 6PG, 6R, 9AT, Cyma 63, 64, 67, 68, 74 - Alloy

Sandsteel Sandalloy Mainspring S3261 for Chezard 60, Bulova 6F, 6PG, 6R, 9AT, Buser 140, 145, Champ 23.7, 28.2, Chezard 60/1, Cyma 63, 64, 67, 68, 74 caliber movements, plus perhaps similar ébauche watches, 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 barely adequate job of representing the item.
