'''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]].

==Overview==

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 [[ETA 2824|2824-2]] is found in lower-end watches. Together with the 2824 and [[Valjoux 7750|7750]], the 2892A2 is one of three common movements from ETA.

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

==ETA Variants==

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

* [[ETA 2892A2]] (1999-present) - 11.5 ligne, 3.6 mm base movement with sweep seconds and quickset date
** [[ETA 2890A9]] (1999-2005) - 5.2 mm height, [[perpetual calendar]] with [[moon phase]]
** [[ETA 2891A9]] (1999-2005) - 5.2 mm height, [[perpetual calendar]] with [[moon phase]] and [[sweep seconds]]
** [[ETA 2893-1]] (2002-present) - 4.1 mm height, [[world time]] disc, quickset date, and [[sweep seconds]]
** [[ETA 2893-2]] (2002-present) - 4.1 mm height, [[dual time zone]] hand, quickset date, and [[sweep seconds]]
** [[ETA 2893-3]] (2002-present) - 4.1 mm height, [[world time]] disc and [[sweep seconds]]
** [[ETA 2895-2]] (1999-present) - 4.35 mm height, quickset date and [[sub seconds]]
** [[ETA 2896]] (2003-present) - 4.85 mm height, quickset [[big date]] and [[sweep seconds]]
** [[ETA 2897]] (2004-present) - 4.85 mm height, [[power reserve indicator]] at 7:00, quickset date, and [[sweep seconds]]

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