First Rolex; Some observations, questions

[ajkenn8545]

So I have wanted a Rolex for some time now, and have always been interested in them, and in anything mechanical really. Just got my first one, a white Milgauss from the forums here.
My first reaction was that I was extremely impressed. I couldn't stop staring at it. Albeit, it was initially a little smaller than I remember it being.

By no means do I have large wrists (5'11" and 160lbs), but it just seemed a little too small. I am already looking at a second Rolex. I cannot decide, but have been narrowing it down. I really wanted a GMT I/II. The blue two tone is really growing on me too (Sub), but I am keeping an open mind. I also really like the look of the new 116710. I think one in black could go well with the white Milgauss. Two watches to go with everything, right?

Any suggestions or advice for me? Also, any side by side comparisons in reference to the size of the Milgauss as well?

Thanks!
