Seriously though, if you want a fancy 'Pilot Watch' because it looks cool, then, by all means buy one.
If you want to know what real pilots have on their wrists, take a walk through a busy airport and ask to see their watches. You will find that, almost invariably, they wear an inexpensive watch with a second sweep hand and a large, clear, simple dial that is easy to read in turbulence.
I still wear a 'FILA' watch made by 'Swatch' That a friend found in a scrap car he was stripping about 20 years ago. It keeps great time, has a second hand, and is very clear to read.
