This lovely Eterna is Anders’ as well, and it’s also in need of a service.
If you are in my generation, you will remember Thor Heyerdahl, and “Ra” and “Kon-tiki” will mean something to you. As my brother was an avid fan and had a couple of Mr. Heyerdahl’s books, I got the connection. An explorer’s watch with a screw-down crown.
The 1489K movement, and if you are familiar with ETA movements, you can already see the similarity. For good reasons, as Eterna developed a fair amount of ETA movements.
This is the first incarnation of the sliding crown wheel with click, and the click wheel on the barrel can move freely in one direction, pushing the crown wheel to the side, and engages in the other direction for manual winding.
The usual old grease in the mainspring barrel.
The bottom plate looks almost experimental. The “Patented” has been chopped off to make room for the cover plate for the date mechanism.
And here it is. Also note that the bottom escape jewel has a cap.
The cut-off “Patented” and the quick-set mechanism.
Ready for the cleaning machine.
The new mainspring goes into the barrel.
Then I fit the balance jewels.
Now I can put the gear train in.
And the base movement is beating.
Nice even beat rate, good amplitude and great beat error.
A very nice looking movement indeed.
The bottom plate comes back together.
Now I can case the movement with a new gasket.
The crown isn’t original, but I can’t get an Eterna crown to fit the pendant tube that’s in the case. Maybe someone replaced the pendant tube at one point.Off across the Pacific!
How could I forget! As Anders suggested, here is the great Kon-Tiki logo on the case back.
