Pilot watch not a real EB6

Hi. I am a bit confused. I saw this watch on Amazon and a reviewer
states it is not a real EB6:

"The E6-B rule bezel is incomplete, however operational. For a perfect
calculation, you must have a "mirror" of the main functions of the
rule bezel printed within the watch, just like any Jeppesen Computer.
Although I knew this when I bought the watch, it's still important to
mention that. There are watches in the market with a complete E6-B
rule bezel."

for this watch:

But I've looked at other watches, like the one I want, and the "slide
rule" seems the same on all of them:

I want a real EB6; what am I missing? Is this guy right? Is the
latter watch true EB6? How do you tell?

Thanks a lot....
