my apologies if this was widely known or assumed. I hadn't read, or heard this before, so i'd thought i'd share it to further the useless amount of information in other's minds as my tiny brain is full.

eterna watch devotees have all seen kontikis labeled 10 and 20. I hadn't really given it much thought, but assumed that it was just another way to label models. but if the catalog information below is correct, it would appear there was a reason for this distinction. the 10 was good to 10 atmospheres- the 20 to 20.

there. that's it. I hope this is interesting to someone.

 

Well done! Hopefully all puzzled Kontiki collectors will find their way here for the answer.

 

That's correct.

And interesting to see the NSA bracelet on the -10.

 

And....
Seppi in a Cooper-Maserati if I'm not mistaken.

Horrid car, but of historical interest
