Probably took you longer to post the thread with all the photos than to sell it. Nice Kontiki.

I have to ask - in what way is the ETA modified? Isn't it Eterna's own movement? 😕

Honest question!

Honest question!

If it is like mine, it came with an Eterna-matic cal 1489K movement. I have heard it was similar to certain ETA ebauches, but with some special features. I'm guessing here, but I imagine that the ball-bearing rotor design was one of the modifications.

Interesting to discuss further, but probably we should not continue to bump this obsolete sales thread. 😁
