The ETA 2773 is a reliable automatic watch movement from the Swiss manufacturer ETA, part of the 2700 series produced from the late 1960s to the early 1980s.
Overview
Introduced around 1969, the ETA 2773 belongs to a family that powered millions of timepieces, emphasizing durability and affordability for mid-range watches.
