The ETA 1081: A Vintage Workhorse Movement
The ETA 1081 is a manual-wind mechanical watch movement launched in 1955 by ETA SA, renowned for its reliability in mid-sized vintage timepieces. Larger than its sibling ETA 1080 at 11.5 lignes (26mm diameter), it shares a similar framework but features a broader mainplate for bigger cases. With beveled edges and hacking seconds capability, it exemplifies Swiss precision engineering from the post-war era.

Historical Context
Introduced during ETA’s expansion phase, the 1081 powered affordable yet durable watches amid the mechanical boom before quartz dominance. Its family includes the smaller 1080 (10.5”’), both emphasizing lever escapement and monometallic balance. Spare parts like barrels and detents remain available for restorers.
