ETA 2892-1488 Reversing Wheel

Product Description

The ETA 2892-1488 Reversing Wheel is a genuine Swiss-made component for the ETA 2892 automatic movement family. As part of the bidirectional automatic winding system, the reversing wheel works with the auxiliary reverser to convert the rotor’s back-and-forth motion into a consistent winding direction, ensuring efficient mainspring tension for the movement’s ~42-hour power reserve. This brand new original part is essential for watchmakers restoring proper automatic winding function when the original reverser becomes worn or damaged .
