HR Mainspring No. 498 for Bulova, Benrus & AS 5 & 6 ligne movements - Steel

HR No. 498 steel mainspring for several AS based 5 & 6 ligne wrist watches; Bulova caliber 5AB-AC-AL-AX & 6AL, Benrus caliber Q and AS caliber 976, 969, 1012, 1025 movements. See images for precise calibers supported and 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.
