ETA 2661

Description

In the early 1970ies, ETA lauched their final movement series of 7 3/4 sized movements. Their variations ranged from a simple handwinding movement with 21600A/h (ETA 2640) to the high-beat selfwinding movement with day and date (ETA 2678).
From this series originates this caliber ETA 2661, a high-beat movement with date display.
