Citizen Nighthawk Black watch
Although I have never owned a Citizen watch until the Nighthawk, I have come away pretty impressed. The watch has a screw down bezel and internal slide rule moves, which is very smooth. The slide rule is a really nice touch, but I would be hard pressed to use it while flying. I am not sure why the black version is more expensive, but I was shopping for something with more of a unique look, and the black casing and band remove it from the sea of silver or leather banded watches. Overall, the watch is quite versatile and I am happy with the purchase.
