Ok then......if ideas are what you are looking for then I would say you should aim for:
A simply-styled, digital readout watch with a square face that gives me the time and date where I am, the time and date at my destination and UTC time - there is absolutely no need for the watch to have a flight computer, as I have said before, it will never be used.
I like clear numerals and while traditional "digital" style ones are ok, a newer "computer" style font would be nice. Like the clocks you see as screensavers on PDAs or an iPhone.
For example: (apologies for my design skills!)
I would also like it to have a stopwatch and a countdown.
Elapsed flight-time would also be nice (separate to the stopwatch).
Pro Trek have a nice feature where the backlight comes on in low light conditions when the watch is tilted towards your face - I would like the option to turn that off if necessary.
A recurring alarm would also be necessary - a nice loud one that actually has the ability to wake a very tired pilot.
(If you want ideas on good screen layouts, have a look at the latest generation of dive computers - not dive watches though.)
Thanks
