All I ever use is the "box" in the airplane. I have a Nike watch that has all of the wiz bang Altimeter, compass, ect. It was about $100, about half of the size of the Sunto, and has been with me for almost 5 years. I have to agree if your going for style, go with the Rolex. Now days you can find the cheapo fake Rolex watches that even have the sweeping second hand not the tell-tale tick-tick-tick of the fake ones. I bought one for $25 last time we were down south. I know it's not real, but the flat screen TV I bought in it's place is.
