ETA's thin high-grade automatic and the base for many modules. ETA product page: 11½ lignes, Ø25.60mm, 3.60mm high, 21 jewels, 28,800 vph, typical power reserve 50h, ETACHRON regulator, bidirectional self-winding, stop-second, semi-instantaneous date with quick correction. Conflict: ETA's older technical communication (CT 2892A2, 13.02.2019) gives a 42h running time; the current product page's 50h is used here. There is no Standard grade; grade figures are from Wikipedia (citing ETA manufacturing information) and Caliber Corner. ETA also labels the 2892A2 product page "unavailable" on its public site. The Sellita SW300-1 is its counterpart.
