Has anyone actually blown up the pictures and looked closely? The watches are fake/redone. Apart from the obviously wrong bezels, the turn-o-graph dial is clearly repainted - the lacquer is uneven and thick near the lume plots, which themselves are shoddily applied, and the writing is not recessed nor the correct font. Also, the metal parts of the hands are too thick and not original. The GMT fonts on the lower half of the dial are all different than the original 6542s with the depth rating, the minute hand the wrong length, and the hour hand is curved, which is not appropriate for the 50s. Pretty easy to find similar fakes through a simple google search:

@Marsimaxam - that's where the picture you put up came from so not sure how you could have "never seen a faked 6542 with depth rating").
@Dan S -- your spidey sense is working fine. The 1665 is too blurry to tell what it is but the lume plots look domed, which is also seen with fakes, and the crown/case dimensions look off.
These are what original ones look like.
Stay away from this guy.
