At the risk of repeating myself....
A good pilot's watch contains the following:
A clean, high contrast face with all numerals and date showing. Non-reflective and non-polarised. (Especially if you are wearing polarised lenses!)
Good size difference between hour and minute and a clearly marked second hand.
Tritium markings on all points. Or high quality luminosity.
A hand to mark out the hour in Zulu time.
An alarm that could wake the dead.
No stopwatch, no slide rule, no compass, no baro, no altimeter.
