BESTFIT Mainspring 612E for ETA caliber 790, Enicar 792, Benrus BP, CA - Alloy

BESTFIT Mainspring 612E for ETA 790, Enicar 792, Benrus BP & CA caliber movements plus perhaps similar ébauche watches (ETA 1240), white alloy, new in envelope. See image 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 pretty good job of representing the item.
