Samson Mainspring No. 7014 for AS caliber 1023, 1030 & Benrus AF, AS - Steel

Samson No. 7014 steel mainspring for AS caliber 1023, 1030 and Benrus caliber AS, AS movements plus perhaps others, new in envelope. See images for precise mainspring specifications. I likely have several of these so the on 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 pretty good job of representing the item.
