The reference Swiss automatic (in production since 1982) and the template for the Sellita SW200-1 and many Chinese copies such as the PT5000. ETA technical communication (06.10.2022) and product page: 11½ lignes, Ø25.60mm, 4.60mm high, 25 jewels, 28,800 vph, power reserve minimum 38h / typical 42h, lift angle 50°, ETACHRON regulator, bidirectional ball-bearing self-winding, stop-second, semi-instantaneous date with quick correction. Older sources often quote 38h, which is ETA's minimum figure. ETA does not publish the grade table on its current pages; the grade figures above come from Wikipedia (citing ETA's archived "levels of component quality" sheet) and Caliber Corner, which agree. Some forum sources give ±30 s/day max. variation for Elaboré. ETA's public site now labels the 2824-2 product page "unavailable".
