Elgin Factory Set Bridge / Set Lever Spring 252A for 18/0s Grade M115 (UTC 28S) movements

One Elgin Set Bridge / Set Lever Spring for 18/0s grade M115 movements, Refill #252A-M115, new in unsealed packaging. The M115 Elgin is a Japan made UTC caliber 28S movement so naturally this part will fit that movement as well. 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.
