Try as I might, I can't find a single other example. It is a bit strange that the font of "diver" is so different from the other lettering, but this happens all the time when there's any collaboration on a piece. Does the caseback have any helpful info?
Yeah, no help there. My £.02, as a long-time fan of Eternas, is to pass on this one. It's super beat-up (esp. the bezel and the caseback), and unless the price is very, very low, you're best off waiting on a model that's received less abuse and doesn't have such atypical dial markings.
Perhaps I’m wrong, but I was under the impression it was an obvious tell the dial was relumed when the numerals were missing. The 12, 6, and 9 hour markers should have numerals.
I did saw a couple online without the numbers
There are plenty online without numerals, but I personally wouldn’t view any of those as benchmark examples. The fact remains that these watches should have numerals, and any example that doesn’t have them, is a watch I wouldn’t consider any further.
