Better response on post RE: Citizen NighthawkIt sure does! Here is some more info on this watch:

The Citizen Nighthawk might be old news to a lot of watch people out there. It’s been around for a few years and has gotten a decent amount of attention in its day. But despite that we felt that it had a place on worn&wound, because it’s one of the best mass-market quartz offerings out there in terms of affordability, good design and value.  For $237, the Nighthawk delivers in ways that many more expensive watches don’t. It has useful complications and features, distinctive looks, solid build quality, good water resistance and a solar powered movement that lasts 180 days on a full charge and never requires a new battery. Forgetting that it is a cool looking watch for a second, between the GMT hand, the slide rule bezel and the solar movement, you have 3 outstanding features that can actually be useful on a daily basis. As James Enloe pointed out in his guide of GMT watches, being able to track a second time zone has very practical implications. Slide rule bezels can allow you to do division, multiplication, convert various distance units and much more on the fly. And knowing that your watch is never going to suddenly stop as long as it sees a little sunlight here and there is a great feeling.


Case: Stainless Steel
Movement: Citizen Eco-Drive GMT solar
Dial: Black
Lens: Mineral Crystal
Case Back: Screw down
strap: Steel Bracelet
Water Res.: 200m
Dimensions: 41mm, 46.3mm lug-to-lug
Thickness: 12.5mm
Lug Width: 22mm
Crown: 6mm Screw down
Weight: 141g
Warranty: 5 year

The Nighthawk has a 41mm stainless steel case with a lightly brushed finished on the body and around the outer bezel. The case is constructed of 3-parts, as is standard, but has a very pronounced outer bezel that houses the internal slide rule. This gives the 12.5mm tall body a slightly greater perceived height. The main portion of the case has a unique form with harsh geometry and strong faceted shapes. It is an interesting form that emphasizes the aviation roots of the watch, and gives it a unique and modern look. At 8 and 3 are two crowns, operating the internal bezel and basic time setting functions, respectfully. Both crowns are straight cylinder shapes with a knurled finish and chunky crown guards protecting them. The knurling provides both excellent grip and a visually pleasing texture. Both crowns also operate very smoothly and are indicative of a good quality build. The crown at 3 also screws down, facilitating the 200m water resistance, and is adorned with a Nighthawk logo. The case back is a standard screw down type made of polished steel. It has a very light etching with basic information and a Citizen Nighthawk logo in the center. The case back could have used a drop more attention, in my opinion.


The overall look of the case is rugged and aggressive. Its design is clearly aircraft inspired, though while having a unique look it does not distract from the dial or feel overly finessed. If anything, it actually does a good job of receding to the background when looking straight on at the watch, as the watch will then appear to be all dial. One thing to note is that 22mm lugs are fairly close into the body, while this makes the watch fit on the wrist well, it can’t handle thick or heavy/leather NATO straps.

When you talk about the Nighthawk, you can’t help but spend most of your time talking about the very intensely information-laden dial and internal slide rule bezel. It is a love-it or hate-it type of dial that at first glance is bewildering, but as you look closer and get used to it, it becomes very clear and easy to read. I’ll reserve talking about the function of the bezel until later, but starting on the outer-edge of the watch you have the angled internal slide rule bezel, which is comprised of a logarithmic scale broken into a multitude of markings in white and red, including numbers, tick marks and a few conversion factors relating to fuel and volume. Stepping down to the dial, on the outer most edge you have another logarithmic scale that corresponds to the internal bezel’s. In addition to the scale there is a second index that relates to time-distance conversion. Visually, this area is very dense and complicated, but once you get a sense of where it ends, you can teach yourself to ignore it when you want to simply tell the time.

The main hour index consists of a series of applied markers that are coated with lume. 1 – 5 and 7 – 11 are rectangular and have a slightly pointed tip, facing the center of the dial. At 12 and 6 there are larger numerals in a slightly decorative font. Aesthetically speaking, the hour index, specifically the 12 and 6, add a touch of retro appeal that creates a nice and well-needed disruption from the otherwise purely informational dial. The added height and lume of the applied markers also separates them visually from the dial beneath. Citizen uses a cool blue lume on this watch that is fairly potent and very nice to look at. Other than the roman-sword styled minute and hour hands, the hour index is the only lumed part of the dial, so when the lights are out, the effect is actually very serene, almost soothing.
At the center of the dial is perhaps my favorite aspect of the watch in terms of clever ways to organize information. The GMT index consists of two nested arcs that sweep about 98 degrees, from 6 – 12, one in white and one in red. Closest to the center is the white index, which indicates from 0 – 12 hours. Surrounding that is the red index, which indicates from 12 -24. Both index extend a little past their end time to create an overlap area (hence the about 8 extra degrees). Now, to read this set of arcs you look at the GMT hand, which is a double-sided hand with airplane shaped pointers. On one end the pointer is white, the other red, and you read the arcs depending on which side is currently over them. These indexes break up the symmetry of the dial and condense some of the information on the dial. In doing so, it helps further organize each piece of information on the face, making for an easier at-a-glance read. The little-double headed GMT hand is also just a great design that looks good, serves a purpose and adds a bit of personality.

The nested arcs also open up area on the right center of the dial, where there is a Citizen Eco-Drive logo, a Nighthawk logo (as both a symbol and written out), and text indicating the water resistance. At 3 there is a date window, which has a white border. The date disc underneath is white with black text. While that is the inverse of the rest of the dial, which tends to make dates stand out too much, given the amount of markings around it, the added contrast helps with legibility. The dial itself is a gloss black that has a slight purple tinge to it, which I believe is due to the solar-energy collecting surface. Overall, the quality of the dial is impeccable. The printing, which gets very fine at points, is crisp and crystal clear and the applied markers, which add a drop of necessary texture, are pristine.

The Nighthawk is a very full-featured watch, designed as a tool for pilots, but is also handy for traveling. The most basic feature, apart from time and date, is the GMT function. This allows you to have two time-zones represented on your watch. On the Nighthawk, in order to set the main time and GMT time separately, you put the crown into first position and by turning the crown away from you, you will make the main hour hand jump forward an hour at a time, without disturbing the minute or GMT hand. The usefulness of this function is undeniable and not only in regards to traveling, perhaps your business has a sister office in a different time zone and you need to keep track of when they are open. Or perhaps you have family overseas and don’t want to call too late…it’s very easy to think of situations in which this complication can come in handy.
The other main feature of the Nighthawk is clearly the slide rule bezel. I’ll be honest, I had never used one of these before getting my hands on this Nighthawk, and at first I was a little intimidated by it. There really is a lot of information, layered on top of itself, that does everything from converting units to indicating how long it takes to travel X distance at X speed to basic division and multiplication. And without a guide on how to use it, it isn’t exactly intuitive. That being said, with a little research one can find out the how-to, and then realize just how practical of a feature this is to have on a watch. So, to give you a head start I’ve included a little video showing you the most basic functions of the slide rule: division, multiplication, conversion of distances, as well as one practical real-life usage. For more complicated tasks, I recommend scouring youtube, as there are plenty of instructional videos there.

One note on the Nighthawk’s slide rule bezel, it doesn’t line up perfectly. When doing calculations, I found that the answer was usually a little off of where it was supposed to be (i.e. in multiplying 30×2, with 30 over the origin, I would find the solution, 60 would be off mark by a hair). While this doesn’t really affect the ways in which I would use the bezel on a daily basis, which would allow for a margin of error, you should be aware that it is there.

Bracelet & Wearability
The Nighthawk comes on a stainless steel bracelet that is surprisingly nice. The bracelet has a typical 3-link Oyster-esque design, but rather than having a relatively flat profile, it has a fairly dramatic tear-shaped profile. This creates a sort of rolling surface over the top of the bracelet that has a very nice texture. Since the surfaces are basically rounded, they pick-up and reflect light in interesting ways, that while not being flashy, still has a certain decorative nature. The build quality is decent enough, it doesn’t feel cheap or light, but at the same time doesn’t feel like an expensive bracelet. It certainly is well enough constructed to hold up in daily wear for a long time. The clasp is very secure and has a double locking system consisting of a standard branded fold-over lock, and then a two-button deployment mechanism.
As I mentioned before, the lugs are too close into the body to allow for particularly thick straps or thick/leather NATO straps. I was able to get a vintage styled leather Hirsch I have on to it, which has a very nice effect. The reddish-brown leather plays well of the occasional red markings on the dial, and the contrast off-white stitching works with the rest. I think this is a necessary option to have for the watch, as it gives it a more casual look that also refers to a classic pilot watch style. Given the overall sportiness and intense technical dial, the leather works to make the watch easier to wear in more situations. The bracelet looks great, but it adds to the severity of the design. It is unfortunate that a classic NATO style wont fit (*update, thinner NATOs can fit, but I had to remove the spring bars and fasten the NATO in, rather than slip through), but brands like Maratac do have 2-piece variations that would probably work and be a great alterative for the warmer months.

The watch wears very well. At 41mm it is a comfortable medium-large size, but given its all-dial design, it appears much larger and really stands out on the wrist. The faceted design of the case matched with the information intensive dial give the watch a fairly aggressive demeanor that can be very eye-catching. In fact, this watch has garnered more attention from people around me than most of my watches. Given the masculine lines, good build, 200m water resistance and bold dial, this is a great option for wearing in active situations, but it still maintains a level of refinement making it welcome at the office and other less casual places.

There are many reasons why the Citizen Nighthawk is a very tempting watch to own. It is rich with useful features like a GMT hand and a slide rule bezel. It has looks that are unique, modern and eye-catching. It is well-built, has good lume, a nice bracelet and is solar-powered. At this point, I would say that these qualities would justify the purchase of a watch costing quite a bit of money, but the Nighthawk comes in at only $237. If you travel often and are looking for an affordable watch to put up with your jet setting, if you are active and want an interesting and different looking sport watch, if you want a modern styled pilot to add to your collection without breaking the bank, the Nighthawk might very well be exactly what you are looking for. *update As per the comment from Mr. Hubbard, I found a link showing the many many different variations of the Nighthawk, including Titanium, PVD and Sapphire versions. And remember that case back I found underwhelming? Well, in Europe and Asia, the watch is available with a highly detailed engraved version…hmm
Nice article for sure, but the fun is only starting now... Do you know how many variations there are of the Nighthawk?
Guide To All the Different Citizen Nighthawk Variants...

I did a bit of looking up on the amazing Citizen Nighthawk. Most of us are already familiar with the U.S version Nighthawk and some own the so-called Euro Nighthawk with that wonderful caseback.

I'm primarily a Seiko collector and the Nighthawk was my first Citizen since 1983. I found the large sunken dial, the pseudo-retrograde GMT hour scale and the highly detailed, internally rotating E6B flight rule bezel quite attractive. The blue lume is also a refreshing departure from the usual green lume in my Seiko collection. 

If you'd like to know a bit about all the Nighthawk models, do read on. [Image: 531a2098fa776821e0338543.gif]

The U.S. Nighthawks
This is probably the most common Nighthawk model sold in North America and to some extent, in the U.K. 

You can easily identify by the Nighthawk text on the dial. Non-U.S. Nighthawks do not have this text. The U.S. Nighthawk also sports full lumed indices and framed Arabic numerals.

[Image: 3b12395847dc2d7a65812132.jpg]

The down side of the U.S. Nighthawk is the plain vanilla, highly polished caseback with laser etched text. Many U.S. Nighthawk owners lamented Citizen's choice of this caseback instead of the highly detailed, engraved satin caseback on the European and Asian variants.

The U.S. Nighthawk caseback vs the non-U.S. version:

[Image: b3dff0a4a11928545473cbe2.jpg][Image: 3aa28e7a3a6293477b6d7650.jpg]

You can easily see why the latter caseback is more desirable among Nighthawk owners. [Image: 531a2098fa776821e0338543.gif] 

There are also variants such as the PVD'ed black S/S and titanium versions. Here is the full lineup of the U.S. Nighthawks:

The Asian Nighthawks

The Asian counterparts of the U.S. Nighthawk come without the "Nighthawk" text on the dial. They also have partly lumed metal indices which help give the dial a classy look. In addition, the "12" and "6" numbers aren't raised like the U.S. versions.

What makes these Nighthawks interesting is the wonderful engraved caseback. [Image: 531a2098fa776821e0338543.gif] 

BJ7010-59E (Stainless Steel)

Newer variations of the Asian Nighthawks appeared recently with the original Citizen deployant leather straps:

The Japanese Nighthawks

Japan market Nighthawks are identified by the "Made in Japan" text located on the dial, at the 8 o'clock position. It's a bit too small to see, but it appears on large photos. JDM Nighthawks are the radio controlled versions and can synchronize the time with LF (Low Frequency) radio time signals on long wave. Alas, the radio controlled Nighthawks lack the 24-hr GMT scale found on the garden variety Nighthawks.

The easiest way to tell a JDM Nighthawk is by the "W.R. 20 Bar" text on the dial.

[Image: 147a3b7c8aafc6f75e2b663c.jpg]
The caseback of the JDM Nighthawk is also richly detailed. The titanium versions are coated with Citizen's famous Duratect plating technology. Interestingly, Duratect is only used on the Japanese titanium versions.

Other interesting variants of the Japan Nighthawks:

PMD56-2771 (S/S version)
[Image: 51f27e1ac6b4e35630d5837f.jpg]
PMD56-2774 (Black leather strap)

PMD56-2775 (Brown dial with matching strap)
[Image: a68c6d9616d4561d3726d84a.jpg]

There are yet other more exotic Nighthawks, such as the PMP56 series with all the bells and whistles. They're the most expensive of the lot and departs from the usual Nighthawk design. You get a dedicated GMT subdial, alarm, three main city times (London, Paris & New York) and perpetual calendar capability. [Image: 531a2098fa776821e0338543.gif] 

[Image: 1705c09f54a11a6c564e742d.jpg]

These "Ultimate" Nighthawks come in two versions:

PMP56-2902 in blue! [Image: 531a2098fa776821e0338543.gif][Image: cb08c9da5b2081415f9f7ffc.jpg]

European Nighthawks 

These Euro Nighthawks are also radio controlled but differ from their Japanese counterparts by the lack of "W.R. 20 Bar" text. In its place, the text "Sapphire" is printed, indicating the use of sapphire crystals, obviously.  European Nighthawks have the model number starting with "AS".

The US version

Great thread guys, keep it up.
Ok, nice thread guys. Makes me want to buy another Nighthawk - but what will I do with this one?
