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

Very good with a few minor flaws.
I just got mine the other day. I own four other Citizen Eco-drive models. They've all been trouble-free and continue to function to this day. The oldest is an 8-year old titaniam diver model. I wanted this new Citizen because it's all black and it's atomic clock accurate. This is a huge watch, but seems to sit well on my smaller wrist. Resizing the band was a bit of a pain as the pins are rather hard to push out. Also, the band is not very flexible, so it doesn't fit as well on a smaller wrist. The one thing that really stood out to me was that the clasp on this watch is of much lower quality than my older citizens with metal bands. This one is made of stamped stainless steel. All my other Citizens have clasps made of thicker solid steel. The watch case itself is solid steel and appears very solid. However, the back is snap-on...eek! Citizen has really gone cheap here. I'd expect that a watch at this price level to have a screw-in back...not a snap-on like a Timex! All my previous Citizen's had screw-in backs. I know that the Japan-only titanium version of this watch has a screw-in back and a solid titanium clasp. This watch is coated black and only time will tell how durable it is. I suspect that eventually the black on the clasp will start wearing off since that's usually where most of the rubbing takes place. The crystal is made of mineral glass and is slightly domed, so at certain angles, you will get reflections. Overall, I love this watch because it looks great and is super accurate. I just wish that Citizen didn't cut down on the quality of the clasp and back to save a few bucks. One other annoying thing is that to access the various functions of the watch (calendar, countdown, chronograph etc), you have to pull out the crown and rotate it. A bit annoying if you use the functions a lot.

Pros:
- very nice looking watch
- fit and finish are top-notch
- bracelet is made from solid links. Not cheap folded metal.
- 200m water resistant
- bezel rotates smoothly
- picks up atomic clock signal in Japan, Europe and North America
- LCD display is backlit, so you can see it at night at the press of a button.
- Eco-drive a proven and reliable technology

Cons:
- cheap clasp
- snap-on back
- metal band not very flexible so if you have a small wrist, you might have large gaps on the sides of the wrist.
- black coating is not protected, so it will eventually wear off.
- crystal prone to reflections

Great watch, but...
I bought this watch because I wanted a more stylish replacement for my Casio. It had to meet two important criteria:
1. It had to set itself atomically
2. It had to be self-powered.
This Citizen watch does both those things, and looks great doing it. It feels incredibly solid, and consequently is a very heavy watch. You might want to go to a jewelry store and try one on. It works amazingly well, sets itself just as advertised, and fits well (with a bit of adjustment at the jewelry store). I've had it for a few days now and it has only a couple of problems:
1. If you're left-handed, as I am, you'll have to take it off to reach the main stem to adjust some settings. Fortunately, you rarely have to do this.
2. For some inexplicable reason, the date setting is tied to the second clock. So, if you live in, say, Los Angeles, and you set the second clock to, for instance, Tokyo, the date shown will match whatever day it is in Tokyo, which is usually tomorrow. If there's a way to change it, I haven't figured it out. So, I have to have both time zones set to the same zone in order to see the correct date.
Other than that, this is an amazing watch, and unless you only value something like a Rolecks as a status symbol, this will feel great on your wrist.

Pros:
- Looks fabulous
- Sets itself
- solar powered
- a lot of dials look impressive
- a slide rule bezel
- battery gauge
- atomic sync in USA, Europe and Japan
- Incredibly solid feel

Cons:
- Not very lefty-friendly (but what watch is, really?)
- Date inexplicably connected to second clock

Great watch
This is a great watch but only reason I am giving it 4 instead of 5 stars is mostly because the band is very very stiff. I figured that after some use and flexing the band that it would loosen up but no its just as stiff as when I got it.

The positives of this watch are:
The band does not grab my arm hair. I have others that I paid more for that will pull the hair off my arm.
Atomic time sync. It is great being able to look at my watch and not have to wonder if I forgot to reset it for daylight savings or not.
Everything my job does is in eastern time and I live in central time so I will set the analog for central and the digital for eastern.

Some of the negatives are:
The very stiff band.
The light on this watch is not that bright and makes the digital part of it to see allot of the time, as well the hands on it the luminescence is not that bright either. So in dark areas this watch can be near useless. I have seen better and have paid more for worse, but one would think for this watch being over $500 that it would not have this issue.

What would had made this a perfect watch:
Better back lighting. I have one watch that when I press the light button it will light up the digital and analog hands as well.
Loosen up the band.
