Dynaflex Mainspring for AS 1023, 1030, GP 88, Benrus AF - Alloy

Dynaflex Mainspring for AS 974, 1006, 1023, 1030, Benrus AF, Bulova 7AD, 7AM, Kurth 340, 360 and Girard Perregaux 88 caliber movements plus perhaps similar ébauche watches, white alloy, new in envelope. See images for precise mainspring specifications. I likely have several of these so the envelopes 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.
