ETA A07.161

ETA A07.161 is an automatic movement with power reserve indicator from ETA. It was introduced in 2005 and remains in production as of 2019.


Mechanical movement in the series ETA Valgranges with self-winding, ball-bearing rotor, unidirectional winding, 48 hours power reserve, hacking seconds device and power reserve indicator. A ball bearing coupling-out system allows a tension release of the indication at the stop after full winding of the mainspring.

The movements of the series Valgranges are an evolution of the famous Valjoux calibre 7750 (hence the name Valgranges, from "Granges" or Grenchen) and with 16½ lignes offer a larger diameter. Thus ETA also provides appropriate large-scale movements for the larger wristwatches that are increasingly common in our days.
