Such as nice, all stainless steel Kontiki rarely comes round. The properties such as a spotless dial, sharp 37,4mm case, near mint Kontiki signed Gay Freres bracelet and signed original crystal underscores this! The crown has the correct Eterna-matic five balls, the yellow gold Kontiki logo on the back (an artist impression of the Thor Heyerdahl expedition raft) and the applied white gold hour markers are intact and beautiful details. How Eterna came to use the Kontiki name is a secret Thor Heyerdahl seemingly never communicated, but is has been in use (and still is) from the nineteen fifties. The extra detail of the dated bracelet 4/66 (4th quarter 1966) adds to the facts that this is a vintage from in our opinion the very best time in the history of mechanical Swiss watches. It has not been serviced by us, but it runs well. The previous owner reports to us that it has been serviced recently.
