## Product Description
The **ETA 2892-1497 Ball Bearing** is a genuine Swiss-made component for the ETA 2892 automatic movement family. As an integral part of the automatic winding system, this ball bearing supports the rotor, enabling smooth, low-friction rotation and efficient bi-directional self-winding. This brand new original part is essential for watchmakers restoring proper automatic winding function when the original rotor bearing becomes worn, noisy, or damaged.

## FAQs
**1. Is this a genuine ETA part?**
Yes, this is a **genuine ETA factory part** (reference 2892-1497), made in Switzerland. The ETA 2892-A2 is recognized as ETA’s premium automatic movement, widely used in mid-range and high-end Swiss watches.
**2. Which movements is this ball bearing compatible with?**
This ball bearing is compatible with **ETA 2890-2, 2892, 2892-2, and 2892A2** calibers. The 2892-A2 is a 25.6 mm movement with a slim 3.6 mm height, extensively used by brands such as IWC, Omega, and Cartier.
**3. How can I tell if the rotor bearing needs replacement?**
A common diagnostic test is the **rotor damping test** – mount the rotor on pegwood, turn it 90 degrees, and let it swing freely. A healthy ETA 2892 rotor should swing for **at least 30 seconds**. If it stops much sooner, the bearing is likely worn and needs replacement. Experienced watchmakers note that the 2892 is particularly sensitive to rotor bearing condition.
