For a long time I used the "watch" part of a heart rate monitor as my daily use watch. I got used to the basic digital watch features (alarm, stopwatch, etc) so I wanted a digital watch for my next one, too. The key points were better looks and durability. I didn't want to risk damaging the heart rate monitor in daily use when a normal watch would serve the same function better.
Then I saw this one and instantly loved the colors. Black with pink numbers and bright orange wristband inside - 1cm of the orange surface shows outside the clasp. The pink is actually very light in practice, not purple like in the picture.
As for durability, I've had it for about five months now. It has tolerated a seven-day arctic ski trek and four months of basic infantry training. It does not leave my wrist even in the shower (full waterproofing). It doesn't have a scratch.
I dress in a utilitarian but non-boring way, with outdoors and "hackerish" overtones and some colorful detail. The watch fits that mode of dress perfectly. It felt somewhat big at first but I got used to it, and have enough forearm width that the visual mass of the watch does not look out of place. The thickness is a bother only occasionally when exercising. Needless to say, I strongly recommend this watch. For the price it's a terrific deal and the reviews from G-Shock owners lead me to believe it will last ten years at least.
I'd like to get a second watch to go with more formal clothing. No idea what kind... the Skagens look good though!
Then I'd like a third watch in "traditional military" style - analog, proper self-illuminating dials and hour markers, waterproof. Like this:
