Yeah, it has a bit of pizzazz that the other ones are lacking. It was also available with a deep blue face and strap, which was my first choice, but it was sold out so I got the one with the colorful accents.
I also have a Citizen Nighthawk in Havana brown that I got in a heist on eBay a few years back. The brown version is apparently hard to find. The knob at the 8 o'clock position turns the slide-rule thingy inside the bezel. It can be used to perform calculations that pilots might want to do. The manual had instructions but I've forgotten how to use it-- it's mostly a novelty, I can't imagine a situation where I'd need to use it. The picture doesn't do justice to how beautiful this watch is, but I seldom wear it-- my Fossil is more comfortable and convenient.

Never seen a circular slider rule watch before'
Used to carry one of these in my shirt pocket.
