I vote for 243 (second version) - solid 60 click bezel, better finish on the side of the bezel, reasonable lume, etc. IMHO, the closest aesthetically But it is not the slytech - it is the new 1000.
239 looks great. Don't own that one though so I don't know.
194 and 202 (slytech sub) are titanium in real life - rep is not.
87 - decent 60 click bezel but dial color sucks and hour marker bezels are not well finished.
64 - Bezel hash marks are too low relative to the gen
24 - If talking about Asian 7750 version it has no bezel markers other than the 4 "numbers". Should have hash marks (24B or later)or be polished with no metal rings around the hour markers (24A)
Of course as I give all these harsh grades I own 4 of the 7.
