You didn't mention your wrist size, but if it's 7.5" or more, I'd suggest going with a ceramic Sub or Sea Dweller. The ingenious variable-length glidelock bracelet (fitted as standard equipment on the dive watches) will ensure a perfect fit out of the box, and will come in handy during your long hot summers, lol. And, imho, you simply can't go wrong with the classic, handsome, iconic beauty of the Sub or SD. I'm also a big GMT and DJ fan, but with a 7.5" wrist, I almost always need an extra bracelet link (the 5mm Easylink extension just doesn't do it for me). As a repeat customer, my AD always helps me achieve a perfect fit. Another strong reason for shopping at an AD. Good luck with your search!
