I have 3 watches I wear with any regularity
One is an aviator watch I bought because I liked it, before I even thought about learning to fly
I have one of these I was given as it’s a nice watch

And one of these which I bought to try and make navigation exercises while flying easier

I can say that the Casio is the most useable by flying by far. The tissot is good as it’s clear and simple and I won’t fly with the citizen. Despite the slide rule, world time etc, its just not clear and useful enough for flying. I couldn’t comprehend using the slide rule while flying
