Citizen Skyhawk for me in Titanium. Very nice - good luminecence, could do with a back light though. I use the whizz-wheel all the time when doing x-country flying. Have deleted time zones to UTC/Auz/NZ. Face is a bit exposed though, prone to scratching.
Also have a G-shock with analogue/digi and world time zones - again have deleted down to Auz/NZ/UTC. Lives in my car in case I forget my Citizen.
