Longines Factory stems for caliber 15.93, set of 2 - new in envelope

TWO Longines factory stems for caliber 15.93 and perhaps other as well, new in open envelope. Package originally had 3 but only 2 remain. 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 an adequate job of representing the item.
