ETA 2892A2

ETA 2892-A2

Cal. 2892A2 (often called 2892-A2) is an ultra-thin automatic watch movement produced by ETA. It was introduced in 1999 and remains in production as of 2019.


The ETA 2892-A2 is the upper-range automatic movement from ETA. It is commonly found in “upscale” Swiss watches, while the older and cheaper 2824-2 is found in lower-end watches. Together with the 2824 and 7750, the 2892A2 is one of three common movements from ETA.

The 2892A2 is an evolution of the 2890 and 2892-2. It is a mechanical movement with automatic winding, ball-bearing rotor, hacking seconds, with power reserve of about 42 hours.

The current ETA calibre lineup includes the following variants of the base 2892A2 movement. All are 11½ lignes (25.6 mm) in diameter, self-winding, 28,800 vph.

The 2892-A2 is the basis for the Omega 1120 and co-axial Omega 2500 calibres which are manufactured specially for Omega.
