Stainless steel with 42mm screw-back case. Featuring our Eco-Drive technology – powered by light, any light. Never needs a battery. Caliber number B877. Since its foundation in 1930, CITIZEN has promoted a multi-cultural mindset that fosters excellence and creativity. The very name of the brand conveys a deep respect toward craftsmanship and considered as familiar by citizens the world-over. So as a “citizen” of the world, we bear the responsibility to help cultivate a culture of positive change and on-going evolution through our craft. We take that mission seriously and steadfastly welcome what the future may bring. As a true manufacture d’horlogerie, CITIZEN integrates a comprehensive manufacturing process from creating individual components to a watch’s final assembly. It’s an artisan’s approach to watch making based on pushing forward the boundaries of technology and leveraging our experience toward exploring new possibilities. One pivotal technological breakthrough was the development of a light-driven watch. CITIZEN pioneered this engineering innovation well ahead of other watch manufacturers as early as 1976, which led to the launch of the highly acclaimed Eco-Drive in 1995. Utilizing electrical power converted from virtually any light source, this extraordinary innovation changed forever the way watches could be powered. Eco-Drive eliminated the need to ever replace batteries, which made it especially beneficial to areas where such specialist batteries were not obtainable. This leveled the field for citizens of virtually every country to be able to experience unrestricted joy of wearing and using a CITIZEN watch. The product development policy, “The Fusion of Technology and Beauty,” remains a constant motivation for us to merge cutting-edge technology with perfection of design beauty, which as a consequence inspires people to strive to be their best at any time. CITIZEN launches a new campaign in collaboration with Wieden+Kennedy, Better Starts Now. This is the simple belief that no matter who you are or what you do, it is always possible to make something better — and now is the time to start doing it. We believe that better and now are both infinite, and that there is always a next ‘better’ and a new ‘now’ in which you can start pursuing it. It was clear from the onset of this project that we are dedicated to this ideal…not to the past but to the present, and all the way we can improve it. To help communicate this belief to the world we have created a new global CITIZEN brand movie, brand identity and brand website that represents out Better Starts Now philosophy.

Review: Excellent watch for the price! - I've had this watch for about 3 weeks now, and really love it! The comments about it being heavy are totally wrong to me. I'm used to wearing a heavy Swiss Army watch, and this is light in comparison. Several users have mentioned that the band feels cheap. From my own experience with other high end watches, I'd say that it does not feel cheap. It is not very thick and heavy feeling, but it does feel solid, and is very comfortable on the wrist. The links are all 100% solid SS, so you know it will last years. Also, love the push button deploy clasp. One other thing that I noticed that no one has mentioned, is that the whole bracelet is brushed SS, EXCEPT at the bottom 1/8th of the middle link it is polished. It really adds to the beauty of the band. Some other observations that go against what others mentioned: 1. I can read the small numbers just fine and I'm 45 years old with about 15/20 eyesight, and don't wear reading glasses. 2. I've used the slide rule functions on several occasions. Tip calculator, large multiplication/division, converting lbs to kg and vice versa. It is a very cool tool. 3. The size on my wrist looks just right. It does not wear very big to me. I think the fashion is getting more towards larger watches, and this would be a maximum large watch for a 6" wrist, but for a 7" wrist, it is not overly large. I would even go 44mm and I think that would be my limit. 4. The lume is exceptional. I can still see it perfectly at 5am with no charge before going to bed. 5. The date window is just fine for my eyes. Just hold it a little closer to your face and you can see just fine. 6. Seconds hand lines up on almost all of the second marks, but there are a few spots around the perimeter that it does not line up. No big deal. 7. Time is right on, measured over 3 weeks against an atomic clock. 8. No chrono and alarm, big deal, don't really need that anyway. 9. Crown screws down nicely and feels fairly solid. 10. The only thing I wish this had was a sapphire crystal. But when it gets scratched, and after the 5 year warranty, I'll have them put on a sapphire crystal. But in the meantime, it really is a beautiful flat crystal that is proud of the top of the watch and bezeled at a 45 degree angle, making it look very nice. 11. The watch came from desertcart charged, so all I had to do was set the time and it has worked fine ever since. I left it on my dashboard a few bright sunny days to charge it while I worked out in the gym, and it has held its charge no problem. Overall, I'd say get this watch if you can get it under $250. It is money well spent. With a 5 year warranty, that is an incredible warranty from desertcart. Not even Tag Heur/Oris/Brietling/Rolex have a warranty like that!
Review: Great Everyday Watch - This was on a "sale" which is a fancy way of saying desertcart's automated pricing algorithm discounted it beyond the usual price point, so I went ahead and pulled the trigger on purchasing one. This has been discontinued now for about two years (2020) so finding this model still NIB is going to start getting to be difficult. First off, I always start out my watch reviews with a disclaimer like this when the price point is low. Don't expect a Rolex for a Timex price. Simple as that. People who complain about it lacking certain qualities or QA not being as precise as an Omega should probably stick to buying Rolex's and Omega's. In my experience, for the price, Citizen puts out a solid product and if I have ever had an issue either a return or warranty repair has been taken with no questions asked. Now on the review.... This is a sharp looking watch. The dial is "busy" but not distracting like some other aviation inspired designs. The GMT function is well done and also visually appealing. The case is a bit on the larger side, but wears fine on a smaller wrist given the shorter lug to lug distance. Some people complain that it is "all dial" but again I don't get this criticism. It simply does NOT wear like a huge, clunky watch. If that is what you desire, there are tons of aviation inspired watches out there that are 45+mm which will suit you just fine. For me, finding something 42mm or under that also fit on to a smaller wrist was a chore and I was quite satisfied with how this product sits. Some people dislike the metal bracelet, but I don't have a problem with it. The links are solid and polished. Clasp is also nicely done. There are enough links to get it customized easily to a small wrist and even has a micro adjust on the clasp to fine tune it. I ended up having to take out every removable link but I also prefer a more snug fit on my wrist. The slide rule is a cool function. I don't know how useful it would be in day to day use when everyone has a calculator on their personal devices, but makes for a nice conversation piece. Takes a little bit to learn how to use, but after watching a few online videos and doing an exercise or two you can acquire the skills necessary to calculate speed, time, distance, and fuel consumption over the Atlantic without any advanced computing devices necessary. Overall, no complaints all around with the styling or quality of the overall product. Now the "down" side, but there aren't many. I really wish it was sapphire crystal and not mineral. Not that I wear even my daily drivers hard, but considering the upgrade here probably would not have significantly increased the overall price of the watch and that this is meant to be more of an "active" sports style I don't see why they went cheap on that feature. Reviews elsewhere run the gamut of the mineral crystal is going to ding up from normal wear to it holds up nicely after years. I don't know what to believe and generally find mineral crystal is fine for day to day casual use. I suspect this will wear nicely for many years to come. Second "con" would be the slide rule is really hard to use in low light due to the black background. I know, I know, this really is going to bother almost no one out there, but still. Why put such a useful tool on a black background without lume? I think white would have looked just fine (and there are a few people on the internet that have modded this watch to have one which looks great). Anyway, this criticism will probably stop zero people from actually purchasing it, but I'll throw it out there just in case the slide rule was your make-or-break purchase point. All in all, buy this watch and get it soon if you are in the market for this particular style. Finding a NIB is going to be hard going forward since it was discontinued back in 2020.

### ⭐⭐⭐⭐⭐ Citizen Nighthawk Is What I Have Been Looking For
*by P***Z on November 11, 2011*

Have been using this watch for a month, pretty happy with the purchase. Excellent buy. Highly recommended! Reasons for 5 star rating: 1. Classy and beautiful looking: It is one of the major reasons which have me made the purchase decision. It has a very classy and serous looking timepiece but with senses of modern technology design. I like the simple face layout and easy to read at any circumstance. Very solid build quality and has a perfect weight (personal favor) on my wrist. 2. Performance and accuracy: This watch runs very accurately so far, I have set this watch in matching with my atomic clock in home when I received it month ago. There is about 6 second ahead of my atomic clock in a month of period. So I can say, it is very accurate and well within manufacturer's +/- 15"/month SPEC. This is the another major reason for keeping make me happy after the purchase. 3. Easy setup and Eco-Drive performance: It is very easy to set up, even for two time zones because there are no too many other fancy features which are not that important to me. Solar battery charge seems very efficient since I never put it directly under the sunlight, it is mostly charged under the standard office light and it runs very smoothly so far. I understand it will take longer time to reach to its full charge. The quick start feature works very good, it only take about 5-10 minutes of normal room light charge to have this watch ramp up from stop to normal running. 4. Other useful features: Slide rule is useful under certain circumstance. I have to wear a pair of eye glass to take advantage of this feature if I need to. 5. Vendor performance: Amazon.com has been one of my most favorite online shopping places. Amazon did same great job on this transaction. Great pricing, on time delivery and, more importantly, Amazon is authorized Citizen dealer, so your watch is covered by the manufacturer's 5 yr warranty. Wonderful buy!!! 6. A few improvements which could make this product even better: * A power reserve gauge which shows the current reserved power level. * A non reflective sapphire glass instead of standard mineral crystal. 7. Other thoughts: Before I purchase this watch I also looked following related models: * Citizen CB0010-53L: which is an AT watch with 26 city world time and perpetual calendar. Local Costco (California) is selling it for $249.00/each which is the best price you can get for this unit. But Nighthawk has much better looking over CB0010-53L. * Citizen JY0040-59L: Blue Angels Skyhawk AT watch with 43 city world time, perpetual calendar and a lot other fancy features. It is a very nice timepiece I almost got that but it's face layout gets a little too busy and cluster and a $200 cost justification which hold me up. * Citizen AT4009-59L: Perpetual AT watch with 5 time zone (US, London plus one customer define zone) atomic time keeping accuracy, perpetual calendar, alarm and non-reflective sapphire glass. In addition, it is an "Eli Manning Limited Edition" (only 1000 pcs supplied globally). Current best retail $540.00/each from Macy's.com. This unit really looks great too. Planned to add this one into my collection by end of this year.
