Longines Factory female stems for caliber L.633, set of 3 - new in package

Set of 3 Longines factory long female stems for caliber L.633 and perhaps other as well, new in sealed package. I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. If you need a part for a Swiss watch I likely have it so feel free to inquire. Images do a pretty good job of representing the item.
