Longines Factory stems for caliber 340, set of 2 - new in package

Set of 2 Longines factory stems for caliber 340 (plus variants) and perhaps other as well, new in open 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.
