The Eterna Kontiki range of sports watch started in 1958 and continues to this very day.  Model number 750.1515.41


From the production dates of the movement we can date this watch to being made circa 1977.  Eterna’s first quartz watch was launched in 1974, and the change to the thinner movements found in the Royal Quartz Kontiki happened in 1979, so we must be quite close.


This watch uses the ESA 9362 movement, which many other companies also used including Heuer in their Kentucky range.  The 7 jewel movement was precise, and this example remains so, and also features a trimmer to allow very precise timekeeping adjustments.  This was done away with in the 1980’s as it was deemed a luxury we could live without.  The screw down case back is engraved with the name Christian Schoop A Rh-.  Quite why Mr. Schoop chose to have his blood type and group engraved on the case back we are not sure – maybe like the original people on board the Kontiki he was an adventurer?

The bezel is likely to be gold, but is not marked as such so we can not guarantee this nor prove the purity.  It is quite worn, and has a few dents, but if this was gold plated then the wear would show the base metal and nothing but gold is showing.  This is a case of patina helping establish the watches credentials!  The matt black dial is excellent, although the lume has dropped out of the hour hand.  The case has clear signs of a previous owner, as shown in the photos.  The strap is new, and the battery will be replaced before the watch is sent out.

This watch will be supplied with our Certificate of Authenticity.
