ETA 2890 Family Overview

The ETA 2890 family is a series of slim and robust automatic watch movements produced by ETA since 1975. They are generally regarded as superior to the similar ETA 2800 family. Cal. 2890 and its successors is based on an Eterna design, with ball bearings on the rotor and a smaller balance wheel in the modern style. The family remains one of the leading watch movements to this day.

The most well-known movement in this series today is Cal. 2892A2, a highly evolved automatic movement with central seconds and a date wheel. Because of its slim dimensions, Cal. 2892A2 is often paired with modules to add world time, power reserve indicator, chronograph, and other complications.

Distinguishing features of the ETA 2890 family include a smaller balance wheel than historic movements, including the ETA 2824 family, and a large rotor hub located with seven visible bearings. The balance is located at 12:00 when viewed from the back with the crown at 9:00, and is located by a clockwise cock with an eccentric screw for regulation.

Most members of the modern 2890 family are available in there finish levels:

  • Elaboré – with nickel balance
  • Top – with Glucydur balance
  • Chronomètre – with Glucydur balance and official chronometer certification

ETA also sells these movements with gold plating, various finishes, and custom rotors.

ETA 2890 Family

Most current ETA 2890 family movements have been updated since the 1990s with improved winding efficiency and an extra jewel in the upper winding bridge. As of 2020, ETA is no longer supplying these movements outside the Swatch Group, with most buyers switching to the clone SW300 family from Sellita. Specifically, Cal. SW300-1 replaces ETA’s 2892A2, Cal. SW330-1 replaces ETA’s GMT 2893-1, and Cal. SW360-1 replaces ETA’s small seconds 2895-2.

ETA 2893 Movements

ETA released a trio of dual time zone movements in 1992, all known as Cal. 2893. Each movement has a slightly different implementation of a 24 hour second time zone display.

DateNo Date
24 Hour DiscETA 2893-1ETA 2893-3
24 Hour HandETA 2893-2

In all three movements, the central 24 hour display is quick-set using the crown in second position and is independent of the central hour hand, which is set using the crown in third position. Adjusting the 24 hour hand or disc does not cause the movement to “hack” or stop, so the timekeeping remains accurate when traveling. Although common today, an independent 24 hour hand like this was somewhat unusual at the time. Indeed, the popular Rolex GMT-Master II Ref. 16710 had just gained an independently-adjustable 24 hour hand four years earlier.

ETA 2890 Family History

This 1975 advertisement in Europa Star shows the key movements in the Ebauches SA family: ETA 2678, AS 5103/5106, ETA 2783, ETA 2824, AS 2063/2066, ETA 2878, FHF 411/412, ETA 2892, AS 5008, and VAL 7750

The original ETA 2890 and 2892 were introduced in 1975 and produced through 1983. These measured 12.5”’ (28.0 mm) in diameter and were designed to be ultra-thin (marketed as “Flatline”) with the option to be used as a base for modular complications. One novel design feature is the fact that the automatic winding gear extends into the base movement, keeping the total profile to just 3.6 mm regardless of whether or not a date complication is fitted. This system used ball bearings for durability, which ETA called “Etarotor”.

The family was revised in 1983 with a narrower 11.5”’ (25.6 mm) width. Most aspects of the design remained, though the no-date 2890 was dropped and official modular movements added to the ETA 2892-2 base: ETA 2893-1 and ETA 2893-3 have a “world time” disc, ETA 2893-2 has an adjustable 24 hour hand, ETA 2894-2 was a modular chronograph, ETA 2895-1 had small seconds, and ETA 2890-9 and ETA 2891-9 had a perpetual calendar mechanism with moon phase. Of these, only the world time ETA2893 series and chronograph ETA 2894-2 remain in production as of 2020.

The third generation appeared in 1996 with the ETA 2892A2. 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. Although the small seconds and perpetual calendar movements were updated (ETA 2895-2, ETA 2890A9, and ETA 2891A9), the chronograph remained in production as-is. New movements were also added: ETA 2896 has a “big date”, and ETA 2897 has a power reserve indicator.

The original ETA 2892 measured 12.5”’ (28.0 mm) in diameter

The revised ETA 2892-2 measured 11.5”’ (25.6 mm) in diameter
Today’s ETA 2892A2 also measures 11.5”’ but features improvements to the winding system
