The Power of Eco-Drive
During the last 75 years Citizen has expanded its business throughout the world and has achieved recognition as the global brand. The past 25-year period has coincided with the company’s dramatic rise to its current position as the world’s largest watchmaker, a distinction Citizen has held every year since 1986.
Beyond sheer size, Citizen is also recognized as a worldwide leader in advanced technology. From the world’s slimmest LCD watch to the first voice recognition watch and the world’s first professional dive watch with an electronic depth sensor, Citizen’s record of "world’s firsts" is unmatched.
More recently, Citizen has staked out a new position as the leader in timekeeping with its Eco-Drives watches that are light powered. With models ranging from dress models to sports models to professional dive watches, Citizen Eco-Drive runs continuously in any kind of natural or artificial light for a lifetime of use. Fueled by light, it never needs a battery.

Sweet watch, I've been wearing mine for 4 months.
I'm an Environmental Engineering Student and I also currently own an Omega Speedmaster ($2100 graduation gift long ago) and a Titanium Pro-Trek Casio Triple Sensor Watch (Compass, Altimeter & Temperature $295.00) that I used for my previous job as an outdoors wilderness instructor.
Both those watches are extreme (the Casio being too rugged, big and bulky the Omega being very freaking expensive) for everyday use and wanted something that suited my keen personality, short budget and modern taste.
I never liked anything in terms of jewelry or watches from department stores or malls, but when I walked into MACY's during Christmas shopping last december at the local mall I saw these Eco-Drive watches for the first time.
It has always been my opinion that Citizen makes very old fashioned timepieces, yet the Nighthawk Eco-Drive is very different and far more classy than any other Citizen watch on the shelf. Some of the other newer Eco-Drive watches also look edgy and fresher. But the nighthawk captures a boldness with it's appearancethat is very timeless. Needless to say, I tried it on and was sold.
The features are amazing, apart from all the other "timekeeping-based and solar powered-based features you can read about everywhere else on the internet, the Nighthawk also has a multi-functional Slide Rule. This is not really praised or mentioned anywhere else so I will tell you what it is, what it does and why it makes owning this watch very cool!
With the slide rule you can calculate your car's fuel consumption, average speed/velocity and the time you will arrive at your destination, you can also multiply and divide numbers, calculate ratio's into percentages, integers and decimals, covert liters to gallons, pounds to kilograms as well as other metric conversions. The slide rule also performs a few more complicated calculations that involve airplanes and nautical vessels that are beyond my understanding.
At any rate, these calculations can be done by simply rotating the NightHawk's bezel and matching specific arrows at certain points along the dial. (If you don't believe me, you can download the Nighhawk's PDF manual and read up on it for yourself.)
In fact, it is easier than using a calculator and clears up the big mystery of what people used before computers and electronic calculators were invented; they used the "Slide Rule".
Being a grad student, I've read about the slide rules in a variety of classes but I never thought that I would own one on my next watch. I also would have never guessed that the slide rule is so efficient and easier to use than the graphics calculators we use in school.
The only negatives cocerning the Slide Rule feature on the NightHawk are the numbers on the slide rule dial are small and angled inwards so that they are tricky to read without tilting the watch around to get a good view of the numbers. Also the slide rule only approximates and produces whole numbers for some of the more advanced calculations.
Overall, I found that the useful geek-features, outdoorsman durability, everyday comfort and eco-friendliness to be well synthesized in the classy steel body of the Nighthawk Eco-Drive.

Great watch:
looks great--I get a lot of comments
doesn't need a battery
fantastic layout--a lot of info at a glance: date, local & zulu times
luminous hands
slide rule easy to use and numbers won't rub out (like on external bezel ring slide rules)
However, for serious aviators:
no stopwatch! You will want a stopwatch to go with the slide rule for basic dead reckoning
you'll need another light source to read the slide rule if you're flying at night
also, the crown has an occasional tendency to work itself loose and you can lose your time hack if you don't tighten it every couple days
The closest I've seen to the elusive "perfect aviator's watch"

This is the first Citizen brand watch I've ever bought, and so far, it's as good or better quality than more expensive TAGs I've owned. About the only thing missing (aside from a stopwatch, as noted earlier - but that's debatable if you're not a serious aviator) is a sapphire crystal, which would probably prevent scratches a little better than the standard mineral crystal. For this price, though, I'm not complaining.
I like the layout, the overall appearance and something else nobody mentioned - the band clasp is a very smart design. Not only does it have something similar to the Rolex "Flip-Lock" clasp, but the main clasp has what can best be described as a squeeze lock, which must be pressed together from the sides of the band to release it from the wrist. This thing isn't coming off accidentally.
I got the stainless version, but there is a titanium one available as well as an all-black version. The all black version looked kinda cheap and the titanium was more money, so stainless was the one I chose. Even though I'm not a pilot, the slide rule is functional (perhaps even useful, in some situations) and the instructions for it are easily understood. All that and a five year warranty. And I always equated Citizen with cheaper-made watches - I stand corrected. No regrets.
