Elgin Factory Set Bridge / Set Lever Spring for 18/0s Grade 747 (AS 1156) movements

One Elgin Set Bridge / Set Lever Spring for 18/0s grade 747 movements, Refill #747-252A, new in packaging. The 747 Elgin is a Swiss made AS caliber 1156 movement so naturally this part will fit many other movements than just the specified Elgin grade. There are some variations to the part, specifically the number of holes, so make sure the ones you need is a 3-hole unit. 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 pretty good job of representing the item.
