Question about Eterna-Matic KonTiki ref. 130T caseback

Hello everyone,


I’m currently considering the acquisition of an Eterna-Matic KonTiki that seems to be a reference 130T in stainless steel. The dial is the more classic silver/white version with baton markers, not the early “black dial with large lume triangle” style (i wish ^^)

What puzzles me is the caseback: it has the KonTiki raft, but it is lightly engraved rather than the usual applied/embossed medallion most KonTikis are known for.


From my research, I understand that the very first generation black dial KonTikis with the large lume triangle did indeed come with engraved casebacks. That’s why I’m wondering:

• Did some of the later 130T models also originally come with engraved casebacks?
• Or is it more likely that this watch has a swapped caseback from an earlier production?
• Does any catalog or documentation clarify which caseback type corresponds to which dial variant?

Any advice or insights before I go ahead with the purchase would be very helpful.


Thanks a lot in advance!
Alex

I just realized my message was ambiguous. My vote is that this is the original caseback, not swapped--I'm not even sure the engraved vs. medallion casebacks are swappable in the first place.

I just checked my own 1st issue Kontiki and as you can see, the caseback number is in the same range. It makes sense there would be a standard (i.e. engraved) caseback used at the time. That's just my £.02, though!

Thanks a lot
