This Eterna Sonic Kontiki is from my personal collection. It had a full service and overhaul two years ago including a replacement date wheel and sapphire crystal. It's a great looking watch, the dial and hands do show some age/patina/flecks which can be seen in the pictures: this looks quite good and adds to the feel of the watch! (the watch dates to the 70s). The screw down case back has the famous gold Eterna Kontiki insert which is in good condition.
Overall it's in good condition for it's age: see close up pictures. The movement is running well, and the date functions correctly: it keeps good time - within the original specification of 2 seconds a day. 42mm by 38mm excluding crown, and comes with a new battery and blue silicone strap that suits it nicely. This Eterna Kontiki the famous 9162 Tuning Fork movement which is widely considered the'Rolls Royce' of Tuning Fork movements. This means the second hand moves around smoothly with no visible steps.
This is a very collectible watch and even be good for everyday wear. Like any vintage watch it shouldn't be considered waterproof.
