ETA caliber 2630 is a vintage automatic watch movement with a day/date complication from the 1970s. This Swiss made caliber is part of ETA’s 2600 family of movements, with a frequency of 3 Hz (21,600 beats per hour) and 25 jewels.

The calendar complication features a quickset date, the day of the week is slowset.

Unlike most ETA movements, there is not much documentation available for the cal. 2630. There are a lot of 2630 examples found in vintage Technos watches, but other brands have featured the movement as well.
