Like MrG I carry the Citizen Titanium Eco-Drive Chronograph ( Quite a mouthful, neh?) and I love this watch. Good for seven years without a change of battery.
It will probably last longer than that, but Citizen recommends you send it in for a full service every seven years, so they can clean it and replace the seals and battery.
I have banged this watch into doorknobs, walls, car doors and what have you. Haven't managed to actually scratch the glass yet. It's probably one of the most comfortable watches I have ever worn and the lock is rocksolid. I don't need no stinkin' Rolex
For really roughing it, I've got a Casio G-Shock that will take a pounding and will light up at night like a damn beacon. The nightlight on the Casio is so bright it will actually ruin my nightvision for about 5 minutes! I prefer the quietly luminescent hands on my Citizen. They'll stay lit all night and won't be as bright as Tritium, and they will last longer than Tritium vials will.
The longevity of Tritium is probably why most high-end watches don't use it. It has a halflife of around ten years and after that, they just stop glowing. Regular luminescent coatings will keep glowing alot longer.
I'll stick with my Citizen for dress and everyday and I might buy one of them Nike watches. Damn comfortable on your wrist!
The Casio and BM CQC7 go together as does the Citizen and my BM 710...Then again, the Citizen goes with all my blades
