====== ETA calibres ======

{{wst>author|[[Foskett, Stephen|Stephen Foskett]] ([[https://grail-watch.com/|Grail Watch]])}}

[[ETA]] is the largest manufacturer of watch movements in Switzerland. The company has taken on most of the Swiss movement industry over the last century, including hundreds of movements.

This page contains information on the main series of calibres from ETA.

===== Eterna calibres =====
Before the emergence of the [[Swatch Group]], ETA was the movement supplier for [[Eterna]] inside [[ASUAG]]/[[Ebauches SA]]. It is here that many common technologies were developed, including the predecessors for the modern [[ETA 2824]]/[[ETA 2836|2836]] and [[ETA 2892]] movements.

===== 2410 Series =====
ETA evolved Eterna's compact 6.75 ligne (ladies) calibre [[Eterna 1419]] into a series of compact automatics for other manufacturers in the 1950's and 1960's. These are the first ETA movements to beat at 21,600 A/h.

    * ETA 2428 - automatic

===== 2450 Series =====
ETA produced this line of compact and popular movements in the 1950's and 1960's, including their successful automatic line. All are 10.5 or 11.5 [[lignes]] in diameter and operate at 18,000 A/h.

===== 2500/2600/2722/2732 Series =====
ETA's mainstream movement line from the 1960's is mostly forgotten today, though it serves as a basis for the modern, well-known [[ETA 2824]] and [[ETA 2836]] movements. Like that family, this group includes 11.5 and 13 ligne movements with both manual and automatic winding. This series was one of the first [[high-beat]] movements from ETA, ranging from the basic 18,000 A/h all the way up to 36,000 A/h for the [[ETA 2732]].

===== 2640 Series =====
This compact movement family is primarily used in ladies watches. It was introduced in [[1971]] and continues in production today. Movements operate at 21,600 or 28,800 A/h and measure 7.75 ligne in diameter. The 2640 series was derived from earlier [[Eterna]] calibres and was also sold by Eterna with an additional "1" preceding the number (e.g., 12660 = 2660).

===== 2750/2760/2770/2780/2790 Series =====
The 2750/2770 family of movements was a mainstream product for ETA through the 1970's, with production beginning around [[1969]] and lasting until [[1982]]. Over 6 million hand-winding and 25 million automatics from this family were made, and they are the predecessor of the modern [[ETA 2824]] family.
