{{wst>image_cr|ETA|2824-2}}

The **ETA 2824** is a family of [[automatic]] movements from [[ETA]]. It is part of the [[ETA 2800]] family of movements. It was introduced in [[1982]] and remains in production [[as of 2019]].

===== History =====
Introduced in 1961, the 2824 traces its roots to the [[Eterna 1427]] design. It began at 18,000 beats per hour but today typically operates at the Swiss standard 28,800 beats per hour, with 36,000 beat versions produced as well. The direct predecessor was Eterna's 1541, which was sampled in [[1967]] with and without the "ETA 2824" stamp.

The 2824 shares a 11½ [[ligne]] (25.6 mm) case diameter with its "big brother", the [[ETA 2892]], though this movement is slightly thicker at 4.6 mm. The 2824 also sports larger wheels and balance and fits the automatic unit entirely above the top plate. It is a mechanical movement with [[automatic]]al winding, ball-bearing [[rotor]], bi-directional winding, [[power reserve]] 38-40 hours, [[hacking seconds]].

This movement is one of the best known and most widely used mechanical movements at all. It is considered to be accurate, robust and reliable. It is delivered by ETA in four quality levels (//Standard, Elaboré, Top// and //Chronomètre//), of which the highest is certifiable as a [[chronometer]].
