Also called 2892-A2 and 2892/A2, Cal. 2892A2 is derived from the similar ETA 2892-2. This third generation of the ETA 2890 family appeared in 1999 and remains in production today. The modification was focused on winding efficiency, with a reduced chamfer increasing the mass of the winding rotor and the switch from a stud to a jewel in the upper winding bridge for the intermediate wheel.
Cal. 2892A2 first appeared in 1999 and is the basis for a number of other ETA movements, including the following:
- ETA 2892A2 (1999-present) – 3.6 mm height, 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
Cal. 2892A2 is available in Elaborate, Top, and Chronometer grade, each with better accuracy and build materials.
Cal. 2892A2 is also known as Maurice Lacroix ML-129, TAG Heuer Calibre 7, and TAG Heuer Calibre 8 RS. It is the basis for Ball RR1101, Ball RR1201, Ball RR1801, Omega 1120, Omega 2500, IWC 30110, 30120, and 37524, and TAG Heuer Calibre 11.
