BESTFIT stem for Gruen caliber V4

One BESTFIT stem for Gruen caliber V4 and possible variants, new in envelope. This is Position Number 425 from the Bestfit #200 Stem System. Yes, the package said 1/4 doz but I crossed that out as there is only one in the envelope.  I specialize is hard to find watch parts so I usually have whatever you might need, all watch parts are unconditionally guaranteed and offers are welcome. Images do an adequate job of representing the item.
