I 'm a ppl student and have looked at many many watches also. To me, theres only 2 things you want to know - the actual present time (utc, of course) and how far into a particular leg of the trip you are.
At just over a hundred quid this is pretty good ...
RW2 Copilote Rallywatch
Or at half that price and the one i actually have ...
Apollogies for the massive links but that what was in the adress bar.
I can seriously recommend the timex as 1- i actually use it and it wokrs a treat and 2;
theres a massive button on the front of it that you just press at the appropriate "turn, time, talk" so no need to mess about holding buttons in while pressing another and hoping you've no just enterred some obscure function and then try for half an hour just to get the stopwatch back !
You can also switch off the digital display and it tries to look like a normal watch.
