My wife got me this Eterna sonic electronic on a recent trip to London! It’s potentially from somewhere between 1970 and 1975ish. I’m unsure of the exact reference or date of production as I haven’t found too much online about these watches. One website I found selling one very similar to this one placed it at 1973, but I don’t know how accurate that is. It’s a tuning fork watch so it hums noticeably in quiet spaces. However, the seconds hand sweeps so smoothly because of that movement which is just beautiful. If anyone has any other information anyone has about this watch I would love to read it!
