Benrus Factory stem for caliber DR, ER - new in envelope

Benrus factory stem for caliber DR, ER and perhaps other as well, new in envelope. I likely have several of these so the one you get may differ slightly from the images. 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.
