Hmmm... I would buy a used Omega Speedmaster Professional (aka. Moonwatch) if I were you. 
Tested it on me... dosent suit me..
my wife and my colleagues say i suit dress watches more...
USD7.4K? wow... cant afford it...
Actually, my analysis on the 3 watches above :
RW - Black = Something new and different to my collections.. (prefer looks no. 2)
RW - White = Something similar to my collections, but it looks stunning to me (prefer looks no. 1)
Longines = Branding and build quality, but looks somewhat similar to my collections too... (prefer looks no. 3)
