The watches are no more than a circular slide rule, which is what an E6B is
(not EB6).

A True E6B or "Air Navigation Computer" or "Flight Computer" will also have
the internal portions used to compute Density Altitude TAS Compressibility
Functions and the "Wind Slide" portion for computing wind correction and
ground speed on the reverse.

I have never seen a "reverse side" to a "Pilot's Watch".

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....
