Bulova factory Balance Staff for caliber 7AM - new

Bulova Factory Balance Staff for caliber 7AM and perhaps other Bulova calibers, new in sealed envelope. See images for further details. I specialize is hard to find watch parts and have a seemly bottomless supply of Bulova parts (Factory and aftermarket) so I'll usually have whatever you might need and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
