Elgin Factory Set Bridge / Minute Wheel Clamp #5711 for 21/0s Grade 617 movements

One Elgin Set Bridge / Minute Wheel Clamp for 21/0s grade 617, 617L, 619, 650, 651, 655, 656, Factory No. 5711, Refill # 617-40, new in packaging. In the varying form of watch vernacular these are called many things, including Minute Wheel Clamp, Set Level Spring, Set Bridges or perhaps even Yokes. 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 a barely adequate job of representing the item.
