Elgin Factory Set Lever / Detent for 11/0s Grade 644, 645 movements

One Elgin Set Lever / Detent for 11/0s grade 644, 645 movements, Refill # 644-138, new in packaging.  These were Swiss based A. Schild movements so it will fit other movements than just the specified Elgin grades. See images for further details. I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. If you need a part for an American watch I likely have it. Images do an adequate job of representing the item.
