Hey guys, I am considering for my next purchase a vintage Eterna Kon-Tiki. I don't really know anything about Eternas and was wondering if there is anything in particular I should be looking for in a 50s or 60s Kon-Tiki. Are they as prone to being redialed as often as Omegas are, what kind of money would a decent one be worth (ballpark), etc. Thanks in advance.
