The Eterna Sonic and tuning fork ranges were launched in 1970, and ran until 1975. Unlike mechanical Eterna watches these do not have serial numbers on the movement, this means we are unable to date this model. Eterna like many other watch companies at the time bought in the ESA 9162 and 9164 tuning fork movements for their Sonic range of watches.

We ask you please make sure you are satisfied with the condition of the watch before purchasing. As these watches are vintage quartz watches they do not fall under our usual guarantee. If you have any questions please feel free to message us.
