I have skinny wrists and tried on the SA in the AD today and fell in love with the white dialled version. even on my skinny wrists the SA looked fine. Only prob is the gen has cream sub dials whilst the reps appear to have silver sub dials. i may have to go with the blue as it seems closer to the gen as far as I can tell, but I fell in love with the white dial and cream sub version. The SA will be my next rep (and last for now as I've bought 4 in the last 10 days). My collection now stands at Blue dialled Chronomat evolution with roman numerals, TT Chronomat evolution with white dial, Navitimer world with blue dial. TT Rolex Yaht Master with white dial. once added the SA will be the daddy of my collection (all the others are quartz or 21j reps). i wanted one high end rep and the SA will be it
