Watches
I have a kickass Breitling. It was actually a gift because my girlfriend thought such a hot aviator should have a hot aviators watch.
The earlier post about real aviators don't need aviator watched is cr*p. I used to have a swatch watch but the hands fell off the first time I went inverted. It also serves as the perfect "I am a pilot" label when you're just about to make a move with the laydeez.
I always roll up my sleeves in the flying club ops room, regardless of the weather, to make sure everyone knows I have the best aviators watch money can buy. That look of envy from the instructors at my local FTO as I consult the watch whilst completing the tech log is simply worth every penny. They may have gold stripes and a blue book, but I have a watch which says "this guy is one of the best flyers in the world, and has the ability AND the cash to fly anything with wings"..
As they say, if you want to be the part you have to look the part....
