ETA 2892-9433 Stop Lever

Product Description

The ETA 2892-9433 Stop Lever is a genuine Swiss-made component for the ETA 2892 automatic movement family. As part of the keyless works mechanism, the stop lever (Article 29) interacts with the setting lever and sliding pinion to define the distinct positions of the winding stem, enabling smooth and reliable switching between winding, date-setting, and time-setting modes. This brand new original part is essential for restoring proper crown function and reliable mode switching when the original stop lever becomes worn or damaged.
