The ETA 2700 family of movements was produced in the 1960s-1970s. The calibers from the 2700 series are considered to be predecessors to the ubiquitous ETA caliber 2824-2 framework that most watch enthusiasts are familiar with today.
Calibers in the ETA 2700 series:
- ETA 2722 – Automatic, 11.5”’, 28,800 bph, time-only (no date)
- ETA 2724 – Automatic, 11.5”’, 28,800 bph, quickset date
- ETA 2728 – Automatic, 11.5”’, 28,800 bph, quickset day/date
- ETA 2732 – Automatic, 11.5”’, 36,000 bph, time-only (no date)
- ETA 2734 – Automatic, 11.5”’, 36,000 bph, quickset date
- ETA 2738 – Automatic, 11.5”’, 36,000 bph, quickset day/date
ETA 27XX Similarities and Differences:
All of the 2700 movements are automatics with a diameter of 11.5 lignes. The differences between calibers is mainly the beat rate (28,800 vs 36,000 bph) and the calendar complication (no-date, date, day date). All of the date or day/date versions are quickset.
Similar Families:
The ETA 2700 family of movements is similar to the 2500 and 2600 series which were produced with lower beat rates.
