Pretty rare Eterna Sonic Gents Electronic Watch from the 1970's.
This Watch was built by Eterna under license from Bulova and uses the Accutron Tuning Fork movement technology within.
The watch itself is in good to very good condition, the case Yellow Gold plate with a steel back, there are some scratches but nothing major, the dial is in excellent condition with very little sign of wear.
Inside the case is an Eterna Sonic Cal 1550/ESA 9164 movement.
Cosmetically overall in good to very good condition and the watch is running very well.
