Watches with loads of functions, including digital stopwatches, I have always found too small (both buttons and displays) and too fiddly to be actually useful anywhere, especially in flight.
The most useful watch I had was a Sekonda that had a digital display as well as the main analog display. I left the digital display on UTC at all times - very handy. It cost about £25 in 2002, but broke a few months ago - I thought the battery had run out, but a new one didn't fix it. No amount of percussive maintenance would coax it back to life.
So I got a very plain Citizen Eco-Drive (no battery to change
). If I ever need one, I'll buy a big old stopwatch and a clip!

ps - I can certainly recommend buying from the USA at the moment!
