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. See more

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.
Review: So far, better than expected! - Well... I'm wearing this watch now and have to say I really like it. Accuracy has been stunningly accurate (It's easy to set the second-hand accurately), as I synchronized it with an atomic-clock-set Casio about 3 weeks ago and the second hands are STILL in perfect synch. In addition, at least on my watch, the second hand is exactly aligned with the second-markings on the watch face. The Casio is also SOLAR POWERED, and that's a REAL benefit. It's the other major selling point for this EcoDrive Citizen. Wore my favorite old TAG Heurer dive watch for about 19 years. The batteries and service cost about $100 every couple or three years, and then TAG stopped supporting it altogether, effectively destroying it. To add insult to injury, TAG offered an insignificant discount off FULL RETAIL on a new TAG watch. Like anybody would pay full price in the first place. I'll never forgive them, and won't buy another TAG again for the shortsighted lapse. The markings on this Citizen glow brightly and last longer than the old TAG Heurer watch ever did but I still can't see the time during a movie that's approaching the 2-hour mark. If your shirtsleeve slips over the dial, you won't have much glow for practical use. It does look great, but the dial marks are more pronounced in person than it looks in the images here. It's no Breitling, after all, and the marks are more "lurid" than the image appears here. One cosmetic minus is the word, "NIGHTHAWK," written on the face. It's juvenile, frankly, and cheapens the otherwise excellent looks of the face. The European market version doesn't have that. Still haven't studied how to use the calculator in the manual, but it's there and I'm sure I can learn it if I take the time. The bracelet is EXCELLENT quality. Strong, heavy, well-made and secure on my wrist. Again, it's MUCH better than my old TAG dive watch (faint praise, but still!). The watch face is a bit larger than I expected but my wrist is big enough that it looks really great. Although the reason I was shopping for a watch in the first place is because I had some user-experience issues with my Casio Waveceptor (buttons too-easily reset the timezone when I moved my hand, and the resin wrist strap is irritating), the cosmetic appeal of this watch is undeniable. I feel great wearing it and find myself checking it out when nobody's looking! Can't think of a single practical reason to downgrade this watch, and if you like the looks and features, there's no reason you shouldn't buy it. If I lost it today I'd buy another. ------- UPDATE: Just wanted to mention that it's now February 8, 2011 and this Citizen watch is STILL entirely in synch with my trusty, atomic-clock driven Casio. The second-hands are exactly together, just as they were in December when I synchronized them. Pretty impressive...! UPDATE 2: Late May 2011 and the watch is still performing perfectly. It's survived some rough work during weekend home improvement projects... both crystal and metal bits are quite sturdy so far.
