It definitely looks legitimate. One of the tells, is the "CARTIER" that is part of the upside down Roman Numeral 'V". It's straight and the "R" comes close to touching.
If you have the energy to take macro shots that would help further... but let's take this approach... I'll post some super close-ups of a genuine Tank Solo 3169 for you to compare in person shortly... best with a magnifying glass or your phone zoomed in.
Note don't compare to photos of other Tank Solo variants in different sizes or even the gold versions as they are slightly different.
