The Citizen Watch Brand

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.

Eco-Drive Frequently Asked Questions (See the full Citizen Eco-Drive FAQ here)

How can you tell if the Eco-Drive watch is getting enough light?
In normal use, the watch displays the time and the sweep-second hand moves in one second intervals. A very important feature of Eco-Drive is the Low Charge Warning Mode which as a result of low battery voltage, causes the second hand to jump two seconds at a time (while still keeping correct time).

How long will an Eco-Drive watch run after it is fully charged?
If your watch is put away where no light is available to it while in a fully charged state, depending on the model, it will run for from 45 days to 5 years.

How can the Eco-Drive watch be recharged?
Besides sunlight, it can be safely charged by exposing it to a fluorescent desk lamp, with the dial (face) up and within about 8 inches or an incandescent lamp (regular light bulb) no closer than 20 inches. Never use a halogen lamp since the heat generated by it can cause damage to your watch. The most efficient and the quickest is in direct bright sunlight (not windowsill) and never on the dashboard of a car.

Customer Reviews

Awesome watch!
Even though I'm not a pilot, I've always liked the Skyhawk/Navihawk titanium line of Citizen watches. My brother is a commercial pilot and has an older one. He loves it. They are just too cool. But I never liked the fact that they didn't have a backlight for the LCD displays. Well now they do! It has an amber backlight that works great. This watch is the new titanium version of the much heavier stainless steel JY0000-53E that came out last year.

Of course the weight of this watch is ridiculously light due to the Titanium construction. For such a big watch, I can hardly tell it's on. I can't stand a heavy watch bouncing on my arm. And be aware, this is definitely a big watch. But that seems to be the trend now (which I like).

The atomic time function works like a charm. I also like having world time at my fingertips. I have family members that live overseas, so it's nice to be able to check their local time at a glance.

It's great knowing I will never have to change batteries with this watch. The solar-powered "Eco-Drive" is an incredible feature that every watch company should have.

The watch has 2 alarms, world time zones (43 cities), solar power, atomic time, a countdown timer, a chronograph, a slide rule, UTC time, a 24 hour clock, ultra-light and nearly indestructable titanium construction, 200 meter waterproof, mineral glass, and it looks outstanding. What more could you want? I think it even does the dishes, bathrooms, and windows. But I haven't looked up those features yet in the 115 page manual (English portion).

One thing that's missing is a one-touch feature to bring all hands to the 12 o'clock position to clear the LCD displays during certain times of day. The hands occasionally obscure your attempts to read the LCD's. Another little gripe is you have to pull out and turn the crown to check the date. And it'll show you the date of your second time zone only. You have to do a couple more steps to get your home zone date if your second time zone is across the dateline from you. I think there's a way to set the LCD 2 to show the date all the time, but I haven't figured out how to do that yet. (Correction 4/1/08: I don't think there is any way you can get LCD 2 to show the date.)

Forget Rolex, Breitling, and Omega. They might look cool and have their high-falutin image, but they have nowhere near the functionality and practicality of this new Citizen. And they all cost about 10 times more. They are also much heavier.

Bottom line: It's virtually indestructable, ultralight, maintenance and adjustment free. I never have to set the time again nor will I ever have to change a battery or put it in a watch-winder (for automatics). I'm a big fan and proud owner of one of the coolest watches on the planet.

Great watch one big issue no easy way to get calendar and dual time together
The GOOD: If you need dual time zone watch this is it. I do deal with India all the time and that is challenge with nearly any other watch. India is 9 1/2 hours yes it is one of the few countries that is a 30 minute offset in time zone and does not change over to DST so then thats 10 1/2 hours just try keeping track of that and things fall apart. There is hardly any watch that will handle a half hour time zone except this one (even the old skyhawk didn't). This watch does that and more including alarms in different time zones so you can set the alarm in another time zone without doing a major compute for the local time. Two alarms so keep one on the local and the second on the world time if you wish. If you deal with London you get a third time zone the UTC sub dial and you can calculate most of Europe easily from that.
The watch is big and thick and in titanium weighs nothing its nearly as light as my kids Casio

The BAD: Contrast on the digital display is pretty bad.
The back light though present is not the best.
The hands cover the digital display a few times a day you can tilt and read under the hands but forget trying to set any function at 20 past the hour

The UGLY (loses one star for this): If you are going to use the second display for a world time zone there is no way to see the local calendar. Just to see the calendar you have to pull the crown 1 stop twist to change the mode and that will give you the calendar of the world zone So to have calendar functionality for local zone you have to set the world zone as your local zone (you lose an easy way to see the world zone). Simply put this watch can work as a dual zone watch or as a calendar watch not as both.

There are 2 nice press buttons one for the light (nice idea) and the other to indicate if the watch was able to sync with the atomic radio signal, it would have been much better if pressing that button would have flashed the local calendar on the display. Citizen could have easily put the atomic signal as an icon on the display. Citizen really dropped the ball on this one I nearly returned the watch due to the loss of calendar but I had got it during a price drop to $510 (Amazon not another vendor) and that sort of let me forget the day and date. Just keep in mind if you must have calendar and world time (besides UTC London) at the same time this watch does NOT do a good job. It does a great job for each (including perpetual calendar) but not both together

Awesome Watch!
So I've had this watch about a week now and I love it! The build quality is awesome and you can tell the Japanese Workmanship is still going strong.

Looks - I think the watch looks great. It is quite big on the wrist but that it looks good for today's standards. It is looks like a heavy duty watch that was given to designers to make elegant. If I had to make a car analogy, I'd say it would have the same feel as if Lexus made a heavy duty truck.

Workmanship - The quality is great. The hands align perfectly on the mark. The second hand ticks where the second hand is supposed to tick which I find annoying if it doesn't. (I've seen omegas that don't even align properly.) The minute hand also moves slightly every time the second hand ticks, the quality is definitely there.

Functions - Calendar, Timer, Chronograph, Alarm 1, Alarm 2, and of course Atomic Time syncronization. There is also a dual time zone function which is very helpful (home time zone and away time zone, you just press a few buttons and it switches them vice versa). The only problem is that if you want to see the current date, it will show the date of the away time zone. This is slightly annoying as to see the current date and time, the zones would need to be set to the same city. The calendar function however would be more helpful to real pilots (which I am not) as they will probably actually land in the away time zone.

Weight - This watch is a good weight, not too heavy, not too light. It is well balanced. This pretty much means that you should expect the non-titanium (i.e. stainless steel) version to be very heavy!

Illuminating hands - at night the illumination is pretty good. There is ample surface area of illumination making it pretty easy to read. The illumination seems to die down pretty quickly however though I haven't tested about how long it lasts. (The watch hands can illuminate briefly in the daytime when you are out in the sun and then walk into a normal lit room, I don't mind it personally.)

Sliding Rule Bezel - I like the function and I think it is really useful. If you take the time to learn this old school calculator, it is really neat and handy. It is best for multiplication and division, it doesn't do addition or subtraction.

Eco Drive - It is hard to tell how well this works, but so far so good.

Overall - I love this watch, it is rugged yet elegant. It also has an extremely impressive set of bells and whistles. The titanium looks good but also makes the watch light enough for wearing all the time without having to think about it. I give it 4.7 stars. Nearly Perfect.
