The ETA 2824-1 is a foundational Swiss automatic mechanical watch movement from ETA SA, renowned for reliability and precision since its development in the 1970s. Often compared to the more common 2824-2 variant, it shares core specs but represents earlier grades with fewer jewels. This workhorse powers countless mid-range watches, offering smooth operation and easy servicing.

History and Development
Introduced around 1972 and refined by 1982, the ETA 2824 series evolved from Eterna Caliber 1427 (1950s). ETA SA, founded in 1856, prioritized ébauches production post-1932 split from Eterna. The 2824-1 denotes base grades, while 2824-2 adds jewels for the automatic rotor.
