ETA 2824-2
Template:File 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 automatical 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.
Ebauche Variants
With Swatch Group curtailing deliveries to third-party customers, Sellita has begun producing a "generic" 2824-2 movement they call the Sellita SW 200. 2824 replacements include:
