A lot of it (like most 'accessories') will depend on your budget.
Some nice ones already mentioned here.
From a practical standpoint, if you're looking at analog watches, for me I like quartz, as I tend to rotate watches, and the quartz is just easier as it keeps ticking away if I don't wear it for a few days.
I also prefer watches with actual numbers on their faces (all 12 if I can get it)...I find them MUCH easier to read, especially on the run.
I think overall, bang for the buck, Victorinox offers some very nice watches. The INOX, with divers as well, looks good and is about bomb proof (literally). Standard INOX left in top picture.
Some of the Deep Blue line seem nice for what they are.
If you want to go a little higher, Tag Heuer has some nice ones, and is a recognized 'Brand' with some status.
I just lucked into a Marathon TSAR (center below), and REALLY like it...this one may take over most of my 'personal time' when I'm not going someplace where I'll take it off (like the gym).
Oh, and FWIW, unless you're really stuck on the 'Analog Diver' Suunto makes some really nice digital watches...the negative (dark) display is distinctive.
Plenty to choose from out there.
Have fun.
