Lot of 2 Stems for Longines caliber 4.21, 3L Movements

Two stems for Longines caliber 4.12, 3L movements and perhaps others as well, new in package. Both could a bit of cleaning before use. 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 a pretty good job of representing the lot.
