Having tried these on instore, I can offer some insights:
-The rotor takes up less real estate in the display caseback, while the black rotor drew the eye away from the internal components
-The blue is very dark, unlike the photos and has a slight reddish hue (under lights)
-The anthracite dial is highly reflective under the bright lights of the AD, this is where the black is best. On the black, the chrome surfaces draw attention while the matt black dial offers a subdued background
-42mm case wears like a perfectly sized sport watch on a 6.5" wrist. It is not a dress watch by any means
-The brown leather band very nice. Might just be the fact that it is different, but the deep chocolate colour works very well for a 'dress watch'
-The white dial is more of a cream colour. Frankly, it's the fashion watch of the lot but it pays the Tag Heuer bills, so I can't hate it. I would never wear it though
