Bulova Factory Reversing Gear Pinion #316C & 317C for caliber 11ALAC, new in sealed 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 an adequate job of representing the item.
