I picked up this very clean looking Eterna Matic KonTiki today at an NAWCC show for a very reasonable price. The dial looks washed out in my pic, but it really is in perfect shape. I changed out the band and gave it some minor service, but it was running great and keeping time when I bought it (I always like to oil a few things when I get something new-to-me).
I don't know a lot about Eterna, even though I have an old bumper automatic. Something about this one said "buy me"! It has a serial number of 4689XXX. Any ideas of how old this may be... 1960s?
Thanks for looking,
