Brand new genuine ETA countersunk head screw designed for ETA 2892 automatic movement series.
Manufactured in Switzerland to original factory specifications, ensuring precise fit and reliable performance during servicing or movement restoration.
A countersunk head screw is designed to sit flush within a component surface. In the ETA 2892 movement, it is used in specific structural or assembly points where:
Precision alignment is critical
Clearance is limited
Even surface pressure is required
Using incorrect screws may result in:
Bridge misalignment
Thread damage
Reduced movement reliability
Professional watchmakers prefer genuine components because they:
✔ Maintain factory tolerances
✔ Ensure thread precision
✔ Reduce risk of cross-threading
✔ Preserve movement value
✔ Support long-term service reliability
Aftermarket screws may differ slightly in thread pitch or hardness, potentially affecting performance.

A: Yes. This is a genuine ETA component, Swiss made.
Q: Can this be used for custom builds?
A: It may be used in builds utilizing ETA 2892 architecture, but always verify specifications.
