ETA 2824/2834/2836-1530 Auxiliary Reversing Wheel

Product Description

The ETA 2824/2834/2836-1530 Auxiliary Reversing Wheel is a genuine Swiss-made component for the ETA 2824, 2834, and 2836 automatic movement family. As a critical part of the bidirectional automatic winding system, the auxiliary reversing wheel works in conjunction with the main reversing wheel to convert the rotor’s back-and-forth motion into a consistent winding direction, ensuring efficient mainspring tension for the movement’s ~38-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.

FAQs

1. Is this a genuine ETA part?

Yes, this is a genuine ETA factory part (reference 1530), made in Switzerland. The ETA 2824-2 is widely regarded as one of the most robust and reliable mechanical movements, first introduced in 1971 and refined through multiple generations .

2. Which movements is this auxiliary reversing wheel compatible with?

This auxiliary reversing wheel is compatible with ETA 2824-2, 2834-2, and 2836-2 movements, a 25.6 mm caliber family widely used in mid-range automatic watches. The dual-reverser system was a key improvement introduced with the 2824-1 generation, ensuring more efficient bidirectional winding .

3. What is the function of the auxiliary reversing wheel?

The auxiliary reversing wheel works with the main reversing wheel in the bidirectional automatic winding system to convert the rotor’s back-and-forth motion into a consistent winding direction . The two reverser wheels ensure that the mainspring is wound regardless of which direction the rotor turns.
