The company was established in 1924. The founding fathers selected the name Citizen so it would be "Close to the Hearts of People Everywhere" and soon after adopted the company’s formal name, Citizen Watch Company. During the last seventy-five years Citizen has expanded its business throughout the world and has achieved recognition as the global brand. The past twenty-five 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 Ecologically Friendly 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.
A serious timepiece for the serious watch collector, the Citizen BJ7000-52E stainless steel men's watch offers powerful timekeeping functions for your favorite aeronaut. The large round watch case measures approximately 43mm in diameter. It has a thin silver bezel the houses a black dial with a pilot's inner rotating slide rule bezel, which is operated by the secondary crown at 8 o'clock. It has large luminous hands and markers for readability and low-light visibility and dual time (GMT) capability.

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.
The watch arrived quickly and my first impressions were very positive. The face is very complex on first glance, but you quickly note the position of the main hour & minute hand and "get" the time very quickly. You can really stare up close at the dial though, there is a ton of detail (more on this in a bit). Overall the "look" of this watch is very appealing. I didn't mention I bought to my wife, and the first night I was wearing it she took a long look and said, "That's a really good looking watch. I really like that" (she normally doesn't pay any attention to my watches. She liked the way it looked so much, she didn't give me too much grief about having bought an Orient the week before!
The bracelet is very nice for a watch in this price range, it's all solid stainless links, but where the bracelet joins the watches' lugs it is just a folded link, not a solid link. The folder over clasp works well and is very secure. I have a large wrist and the bracelet is PLENTY long enough for me. I actually had to make it a smidge smaller with the micro-adjustment on the clasp. The bracelet is subtly brushed, and so far seems to be wearing well (I work at a desk & use a computer all day). There are some desk marks, but they're very minor. The Orient I just bought scratches much more easily, so I'm happy with the durability of the bracelet so far.
The bezel on this watch is a slide rule. There is a crown at the 8 o'clock position that controls the movement of the bezel. It's extremely smooth and seems to let you move it in very fine increments. You can use the slide rule for division, multiplication, unit conversion, and rate/time/distance calculations. It works and you can do it. It's sort of a neat party trick, but I doubt I'll ever find myself in a situation where I was relying on my watch's slide rule to save the day. This watch is billed as a flight watch so maybe there are still some pilots who do things the old-fashioned way and do their calculations by hand? If you want to know how to use the slide rule check out this video: [...]
There is also a GMT face. You can see it on the left side (from 6 to 12) with white & red numbers. There is a separate, double-ended hand with a red-tipped and white-tipped indicator. Out of the box it shows the 24-hour time (white for 00-12 and red for 13 - 24). You can set this to a different hour to have a true GMT indicator. It's a nice feature, and looks interesting, but I don't find I pay much attention to this "sub-dial" really other than what it adds to overall appeal (for me anyway).
The performance of my watch has been good. It's quartz, so it will be more accurate than an automatic watch. It does not sync itself to any of the atomic clocks (like the Citizen Skyhawk does) so I expect I'll eventually have to adjust it for accuracy one of these days.
The lume on the watch is nice and bright - a blue color which is different from the traditional green lume. I haven't gone out of my way to to expose it to bright light, but it's easy enough to read in the middle of the night when I wake up. The lume overall on my Seiko Black Monster is stronger, longer, but this is no problem to see in a dark room even after 5+ hours. I think the size of the hour & minute hand really help; they're very thick and hold a lot of lume.
I am very happy to have this watch in my collection, but my wife gave me the "oh really" look since I just bought another watch about a week before this one!
* Looks fantastic in person
* Large enough bracelet for good-sized wrist
* Screw-down crowns for time/date & day
* 200M WR rating
* Solid links on bracelet (for all but end links)
* Good lume on numbers & hands - lume last a long time (plus cool, blue color)
* Eco-drive should last 10+ years (Citizen says they have examples w/ 20+ years on them now)
* Positive comments from the wife & co-workers abound!
* The date is a little small, could be a tad bigger & easier to read.
* Folded links at the ends (not solid)
* No lume on second hand or GMT hand(s)
* Uses mineral crystal, could scratch easier than sapphire
* No radio to sync automatically to atomic clock
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.
