This vintage 1970s Eterna Sonic electronic wristwatch is a bold and uncommon model featuring a gold-on-steel case, original Eterna bracelet, and a Swiss tuning-fork movement licensed by Bulova. The watch has been recently serviced, fitted with a new battery, and runs nicely.
The champagne dial retains its warm vintage tone with applied markers and a date window at 4 o’clock. The original crystal shows light age-related wear. The case has some plating wear as expected for its age, adding authentic retro character.
