The ETA 2890 is a renowned slim automatic watch movement from ETA, part of the Swatch Group’s flagship lineup, celebrated for its reliability and versatility in luxury timepieces.
History and Development
Introduced in 1975, the ETA 2890 family evolved from Eterna’s Cal. 1466U, incorporating innovations like ball bearings on the rotor and a compact balance wheel for superior performance over the ETA 2800 series. Updated versions, such as the 2892A2 in 1996, improved winding efficiency with an extra jewel and larger rotor mass. Production shifted post-2021, with Sellita’s SW300 clones replacing it outside Swatch Group.
