Pretty much any Seiko chronograph will have a second time
zone on a small clock. They even have an alarm on it though
you wouldn't hear it in a plane! I've had one for a few years now
and it's still on the first battery (seem to remember I bought it
in 1997 but I wouldn't swear by that). It's also got a stopwatch
feature on it, but I don't tend to use it while flying.

The one feature on a clock that I truly do use and appreciate is GMT time.
I can do it in my head but appreciate a visual reference

So what do I want for Christmas? A simple GMT watch. No whiz wheel, stop
watch, alarm or whatever. Just the ability to show me local and/or GMT
time.
