I like the white dial Roman numerals LUC 1937 Classic model best. The numerals on the white dial really 'pop' and the crown is in a sensible position.
I find the 4 o'clock crown position just unuusal and difficult to turn on the wrist. I can see the 'logic' of the position for some people with large crowns because it hurts to cock their wrist back against the crown at 3 o'clock position. But the LUC crowns are quite small so that reason is moot.
Quite aside from that, I like the kooky character that Jim Parsons plays -- Sheldon Cooper: super geek in 26 dimensions.
