ETA 2895-1

by

ETA’s 2895-1 is a modular small seconds movement produced from 1997 to 2000. It is based on the ETA 2892-2, part of the second generation of the ETA 2890 family. The replacement, ETA 2895-2, based on the updated ETA 2892A2, was introduced in 1999.

The ETA 2895-1 paired a small seconds module with the ETA 2892-2 base. This increased thickness from 3.6 mm to 4.35 mm.

ETA 2895-2

by

ETA’s 2895-2 is a modular movement with small seconds and date. It is derived from the similar ETA 2892A2 and is part of the third-generation ETA 2890 family. Cal. 2895-2 appeared in 1999, replacing ETA 2895-1, alongside the base movement and remains in production today.

The small seconds module adds 6 jewels and 0.75 mm in thickness.

Cal. 2895-2 is also sold as Ball Cal. RR103 and TAG Heuer Calibre 6.

ETA 2892A2

by

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.

Since most patents used are expired, numerous clones are made of ETA’s 2892A2. These include Sea-Gull ST1812, Soprod A-10, and Valanvron VAL-92.
