Its the dial and the sub that really set it apart, but you are totally correct, its very difficult to capture in a picture, its MUCH nicer still in the flesh and on the wrist.
The subdial also goes from deep blue to light blue depending on angle and lighting.
The grey manuals are great, would make a fantastic addition along side your metallic blue dialed cal15 i think...

: Very nice couple of Monaco's Richard. I have a 1533B and haven't
: seen a 'G' in the flesh but they do look amazing. My only
: concern may be the shiny dial and matt finish sub dial but maybe
: they look better when viewed in person? I also like your 73633G.
: This would be my next Monaco purchase I think, even though the
: 1133B was my initial Monaco of choice. Now however, although I
: still really like it, my eyes have been opened to the other
: lesser known models. How things change eh...
: Put some more pics on of your 2 if you get the chance.
